Are you one of those who gets scared by all these ever so daunting motoring terms? The one who gets confused between what drives the wheels and what drives the car? Well, fear no more! We at OnCars understand your plight. We know that everyone who drives a car has not necessarily done a stint in an engineering college, because we too haven’t! So to help you out and your fellow comrades, we have prepared an exhaustive list of all the basic motoring-related terms, two-wheelers and four-wheelers included, so you too can brag about your knowledge of torque and horsepower!
these are some of Automotive terminology glossary that can be mentioned in front of you
What are the Specifications?
The specifications reveal the capacity of a vehicle in terms of displacement, number of cylinders, power output, and torque delivery. Specifications, as combined terms, tells you all the relevant information that you need to know about certain petrol or a diesel engine. Putting the engine specifications of one motor with the other, you can judge which one is the better out of the two.
What is a Petrol Engine?
It is an internal combustion engine which runs on petrol fuel. The petrol engine provides power to the crankshaft after the mixture of fuel and air causes a burst of power which in turn powers the piston.
What is a Diesel Engine?
The diesel engine is similar to a petrol engine in the sense that both are internal combustion engines. A diesel engine works when gas is compressed by the piston which generates heat that meets a mist of fuel that has been sprayed through a fuel injection system into the cylinder. The fuel and the hot air mix with each other and explode without the need for any spark plug. The lack of a spark plug allows for easy compression of fuel and higher efficiency.
What is Power / BHP?
BHP stands for Brake Horse Power and is the common unit that is used to measure the power of any vehicle. It is measured by keeping the vehicle unit on a flywheel a.k.a. dynamometer. On the other hand, HP (horsepower) is the maximum power produced by the vehicle before it is transferred to the drive train.
What is Torque / NM?
Torque is the real testament to the strength that an engine possesses and diesel engines have higher torque than petrol-powered engines. Torque is the force with which a vehicle accelerates, thus it is the torque that makes a vehicle move forward and not the horsepower.
What Is Engine Displacement?
It is the capacity of the engine which is the max amount of air that the engine can displace when the piston completes the four-stroke cycle once. It is often measured in CC (cubic capacity) or liters in cars.
What is a Transmission unit?
Transmission is connected to the engine via clutch which can be disengaged by pressing the pedal or a lever and ultimately leads to removal of torque. The transmission helps select gear ratios which usually consist of 5 or 6 forward gears with a reverse gear. Other transmissions on offer are AMT (automated manual transmission, dual-clutch automatic, CVT (continuously variable transmission), and semi-automatic transmission.
What are Engine Valves?
A cylinder has an intake valve and an exit valve just like a human heart and both valves open and close to control the flow of fuel into the combustion cell.
What does Mileage / Fuel efficiency mean?
This refers to the distance that a vehicle can travel on a single unit of fuel. The units of fuel and distance traveled are different at places.
How does Suspension works?
A suspension maximizes the friction between the wheels and the road surface thus preventing the least possible amount of imperfections and undulations of the road to the passengers.
How does a Brake System work?
The braking system is as important as the engine because it helps in bringing a vehicle to a stop. A brake is a mechanical device that hampers the vehicular motion for slowing it down by applying friction to the wheels or axle.
What is Tyre Size?
Tire size is the width of the rubber that is worn by the rims. The tire size is mentioned on the side profile of the rubber in mm (millimeters).
What are Alloy Wheels?
Alloy wheels are lighter than normal steel wheels and allow better performance in a vehicle. Alloy wheels are visually appealing as well because they can be painted, polished, chromed, or machined which gives them a sense of individuality as well.
