Everyone remembers their family car growing up. You remember the way it smelled and how the seats felt. You remember arguing over the front seat and tossing your sports equipment in the trunk. And you remember, after a long day at school, how you’d doze off in the backseat as the radio played.
That vehicle did a lot of work. For a couple of hours in the day, it was your transportation, your lounge area, and your entertainment. As a parent now, it’s your turn to provide that vehicle for your family.
Although you may not have realized it until now, your parents put a lot of thought into what vehicle to choose. Like them, you want to pick the perfect automobile to safely and snugly transport your precious cargo. Unlike them, however, you have the internet at your disposal!
In this article, let’s discuss the four key considerations to make when shopping for the perfect family vehicle.
Safety is priority number one when researching family vehicles. That hot two-door sports car might have looked fantastic when you were 20, but now that you’ve got a family to protect, you want something more robust.
Look for vehicles like the Ford F-150 that have a five-star safety rating from the National Highway Traffic Safety Administration – the preeminent safety testing body. To dig deeper, you can look at crash test performance and vehicle safety features. Where your family is concerned, don’t settle for less than a five-star rating.
Look For Storage Space
Between their sports, your grocery shopping, their music lessons, and your work – that’s a lot of cargo. And that doesn’t even factor in camping trips, fishing trips, and ski vacations.
The perfect family vehicle should have plenty of space for storage. One of the reasons why trucks (like the above-mentioned Ford F-150) are becoming so popular among new families is that, in addition to safety and seating, their large beds are ideal for storage. Plus, it’s simple to find a Ford F-150 at a reasonable price, meaning you keep more money in your pocket for what matters: family.
A Great Infotainment System Goes A Long Way
Kids are a restless lot. Without entertainment and engagement, they resort to arguing, fidgeting, and kicking your seat. That’s why a quality infotainment system is critical.
Look for vehicles that feature a great sound system, intuitive navigational system, and easy-to-use climate control. Then, pop in an audiobook or turn up your kids’ favorite tunes, and wait for them to relax.
Find Seating For The Family Size You Want
Too often, parents make the mistake of buying a vehicle for the family they have– not the one they want. If you plan on having more kids, plan ahead by ensuring your family vehicle has the requisite seating. If you plan on enrolling your kids in after school activities that require storage space, factor that into your decision-making as well.
You remember what it was like to ride in your family vehicle as a kid. You wanted to feel safe, comfortable, and entertained. When you choose your new family vehicle, keep those criteria in mind.
Everything you need to know about turbochargers
Turbocharger, or turbo as it is commonly referred to, is a common word among automobile enthusiasts. Most Americans have come to associate the word turbo with high automobile speed. Considering the work that’s turbochargers do, it’s an apt association.
With the recent impact of racing movies like fast and furious and death race, the concept of turbocharging cars is more popular than ever before. A lot of people have taken to improving their cars with turbos from Goldfarb Inc and other similar stores.
Turbochargers are induction machines that increase the efficiency of the internal combustion in a car’s engine by forcing more air into the combustion chamber. Typical engines require atmospheric pressure to help air suction into the combustion chamber. With Turbochargers, the forced air suction triggers a proportional amount of fuel, the combustion of which makes more power available for the driver.
Turbochargers are not popular just because they increase the speed of a car; they’re also well-loved because they improve engine fuel efficiency. Turbos are connected in such a way that they take in waste power from a car’s exhaust and use it to compress air before letting it out into the combustion chamber. This ensures that every joule of energy is used up before being passed off as waste. Incidentally, the energy efficiency of turbos also makes them great for reducing emissions from cars.
Car manufacturers also love turbo because it helps them utilize smaller and lighter engines while achieving high energy efficiency. In Europe over 75% of the cars to be produced in 2020 are expected to have turbo engines. The USA is expected to hit similar numbers of turbo engine cars in 5 years from then.
It is legal to install turbos in most states in the US provided your car stays below the emission limits. Turbochargers can be used in both gasoline and diesel-powered cars. Since they’re more common in diesel engines, they’re also commonplace in trucks. It’s, however in aircraft that they find the most use. They are crucial to the aerodynamics required for flight.
How Turbochargers work
The exhaust of cars contains hot gases coming out speed. These gases contain heat and kinetic energy that is typically let out into the atmosphere as waste. Turbos make use of this hot gas to compress the air that it sucks in. They then push this air into the engine cylinders, allowing them to burn more fuel and produce more power.
That’s the easy explanation. To really understand how a turbo works, you have to take a look at its most essential parts. The parts are typically replaceable and can be substituted to improve performance. Here are the most important parts of a turbine:
- Turbine: a turbine is essentially a fan that is placed along the path of the exhaust stream. When the hot exhaust steam flows past it, it rotates the turbine. This rotational speed can go as fast as 250,000 rpm. The motion from the turbine is used to generate motion in the compressor. The characteristics of the turbine, especially the size and number of blades, have a significant effect on the efficiency of a turbocharger.
- Compressor: the compressor’s job is to increase air intake into the combustion chamber. It is made up of an impeller (another fan) a diffuser and a volute housing. The impellers blades draw in air as they rotate. This air is transferred to the diffuser where it is compressed and finally sent into the combustion chamber through the volute housing.
- Centre Hub Rotating Assembly: it contains the shaft linking the compressor impeller and the turbine to transmit motion from one to the other.
Types Of Turbochargers
In a bid to improve efficiency, turbos have come in a few different designs over time. Here are some of the popular ones:
- Twin-turbo: this design involves placing two Turbochargers side by side either in series or in parallel. In parallel, both the turbine of turbochargers are each fed by half of the exhaust’s effluent. On the other hand, the series configuration requires one turbo usually at a lower velocity feeding into another turbo of a predetermined speed.
- Twin scroll turbo: also known as a divided turbo, it typically contains two exhaust gas inlets and two nozzles (pressure outlets). The design can be made to have a smaller, sharper angle that reduces response time or a larger, less angle to increase performance.
- Variable geometry turbo: this category of turbo uses movable vanes to regulate the airflow into the turbine, therefore, allowing for optimal use.
Advantages of Turbochargers
- Increased power: turbos increase the airflow into the combustion chamber. This, in turn, causes a proportional increase in fuel combusted, thereby making more power available per second to the car driver. Using a turbocharger, you get more power output from the engine on every stroke of the piston than without one.
- Increased Fuel efficiency: using a turbo with an engine typically results in more fuel consumption per piston stroke. While that is true, it also means that a smaller engine can be paired with a turbocharger to generate similar results as a bigger engine. In practice, a turbocharger can save up to 10% of fuel consumption.
- Cleaner emissions: Since the hot gases in the exhaust, it ensures that the fuel is thoroughly burnt. This resulting gas that is passed out is significantly cleaner than from a regular exhaust.
Disadvantages of Turbochargers
- Turbochargers add to the complexity of a car’s engine.
- Turbochargers result in increased pressure and temperature around a car’s engine, typically resulting in shorter lifespans for engines.
- Turbocharged cars can be tricky to drive due to a lag in initiation time.
Turbochargers vs Superchargers
Although turbos were initially classified as superchargers, there are stark differences between both types of equipment. They both have a similar function in that they use forced induction to increase the power available in an automobile.
The main difference between both is how they derive energy. While turbos make use of the heat and kinetic energy from the car’s exhaust, superchargers rely on energy from the car’s crankshaft.
Turbos have the advantage of being able to provide more power, fuel economy and cleaner emissions over superchargers. However, the linear production of power form superchargers makes for a smoother experience when bumping up the speed.
How Servo Motors changed the industry
Servo motors have been around for over a hundred years, helping to transform the industrial world. The original servo motors were large and weak when compared to the servo motors we use now.
Today, servo motors take the form of small, powerful, and energy-efficient devices used in robotics, manufacturing, and the pharmaceutical and food industries.
Servo motors have proven to be an essential piece of gear that has helped many industries scale up with phenomenal speed. New levels of efficiency and productivity have been reached utilizing their power.
What Is a Servo Motor?
Servo motors are utilized for pushing or rotating objects with incredible precision. If you have an application that requires an object to be pushed and rotated at precise angles or distance, then a servo motor is adept.
The motor is quite simple and runs through a servo system. A DC powered motor is called a DC servo motor, and an AC powered motor is called an AC servo motor. Modern servo motors are capable of producing very high torque yet are small and light in their design. This performance capability has made servo motors incredibly useful for many technologies and across many industries.
Servo motors are most commonly used for:
- In-line manufacturing robotics
- Pharmaceutical and food production
- Flying drones (remote-controlled helicopters/planes)
Servo motors are measured in kg/cm (kilogram per centimeter). The kg/cm indicates how much weight the servo motor can shift at a specific distance.
For example, a 7.5 kg/cm servo motor can lift 7.5kg when the load is suspended 1cm away from the shaft. The motor shaft is positioned at a precise angle using the control signal. Today, manufacturers have started to produce servo motors designed for incredibly useful applications such as robot arms, drones, in-line manufacturing robotic automation, or any object required to move at a precise angle.
How Do Servo Motors Work?
The circuitry is built inside the servo motor unit with a positionable shaft. This shaft is typically fitted with a gear. An electric signal controls the motor, which then determines the movement of the shaft.
The electrical pulse width modulation (PWM) controls the servo motor through a control wire. This pulse is made up of a minimum pulse, maximum pulse, and repetition rate. Servo motors typically move at a 90° either way for a 180° movement. The neutral position is where the servo has equal rotation capability in either direction.
The position of the shaft is determined by the electrical pulse when sent to the servo motor. Depending on the duration of the pulse, sent via the control wire, the rotor can turn to the desired position with high precision and speed.
The Difference Between a Motor and a Servo Motor
There are some key differences between a regular DC motor and a servo motor. These can be broken down by the following factors.
DC motors are made up of a two-wire system, known as a power and ground system. A servo motor has a three-wire system, known as power, ground, and control.
A DC motor is an individual machine that requires no assembly. This differs from a servo motor, which has four parts: motor, gearing set, control circuit, and position sensor.
A DC motor rotates on a continuous basis. A servo motor is limited to 180° and does not rotate freely or continuously like a DC motor.
DC motors are in cars, wheels, various tools, wind turbines, and appliances, where continuous rotation is useful. Servo motors are designed to help with precision movements such as that of a robotic arm or drone.
Therefore, a servo motor is much like a DC motor, but it doesn’t run continuously. Instead, it runs precisely as and when it needs to, which can significantly improve energy efficiency and skill of work completed. For these reasons, servo motors are extremely useful for the automating industry, where large quantities of objects require ultra-fast and precision work.
Servo Motor Accuracy
The typical accuracy of a servo motor is around +/-0.05 deg. This achieved with an encoder. The motor rotates, and an electrical signal is delivered to the servo driver, which informs it on its current speed and position. A servo motor is only ever as accurate as it’s encoder’s accuracy.
When comparing a servo motor to AC or DC motors, servo’s have a clear advantage in terms of speed, high peak torque, and acceleration. A servo motor is capable of operating at speeds of up to 5,000 rpm or more. The closed-loop positioning capability far exceeds the typical positioning capabilities of other speed motors and drives.
