All You Need to Know About Engine Torque
In physics, the torque is a perpendicular force that acts over a pivot point with the help of an arm. Rotational force is another name for the toque that clearly elaborates its meaning and function. Moreover, the rotational force or torque in cars play a significant role in internal combustion engines. From the engine to the driveshaft, torque is one of the most essential elements in a car..
Let’s discuss the engine torque, its role and its significance in the vehicles.
What is Torque in Cars?
Torque is the rotational force that is responsible for spinning the objects. In vehicles, the torque refers to the rotational force generated by the crankshaft and exerted on the driveshaft. The unit of torque is Newton Meter (Nm) where; Newton (N) represents the force that is acting on the driveshaft, and Meter (m) is the length of the driveshaft. The unit of torque is used to estimate the performance of a vehicle. See the following paragraphs, which further elaborate what is the torque of a car and how it works
How Torque Works
Internal Combustion Engine
The engine torque is generated by the pistons moving back and forth causing a continuous movement or rotation on the crankshaft. The energy generated on the crankshaft is then transferred to the wheels through the gear transmission system or drivetrain. The torque powers the drivetrain with additional energy to move the vehicle in low gear. Therefore, the consumption of torque reduces, as the vehicle moves to high speed or higher gears. The torque varies from vehicle to vehicle depending upon a wide range of factors. For an average sedan 400 Nm of torque is considered ideal. Hybrid, petrol and diesel engines use torque in more or less similar manner; however, electric cars have different methods of using it.
Electric cars are more efficient in achieving high-speed instantly contrary to internal combustion engine cars. The main reason for this is the usage of electricity instead of mechanical energy. In internal combustion engines, fuel is burned to rotate the crankshaft and produce energy. Whereas, electric engines use electricity that travels through a magnetic medium and instantly powers the engine. Thus, the electric current instantly generates the drive required to rotate the drivetrain and can speed the car from 0 to 100 km/h within seconds. This is the major difference between the engine torque of combustion and electric engines.
Role of Torque in a Vehicle
Torque is considered a crucial element in the engine’s power generation process. It also represents the total engine capacity of generating power and rotating axis. Torque is more than just a rotation force for the axis. Here we have listed important roles of torque in a car.
Driving through Terrains
It is the engine torque that provides a vehicle with enough energy to drive through multiple terrains. In modern vehicles, the car computer automatically adjusts torque supply to the wheels for coping with different road situations.
Engine torque is the force that estimates the overall load capacity of the vehicle. The higher the torque the higher the cargo capacity of the vehicle. Therefore, 4×4 cars and trucks have higher torque, so that they can carry additional weight.
Driveability and Efficiency
The torque increases the driveability conditions and engine efficiency. The adequate amount of torque supply reduces engine bumps. Moreover, complete combustion and smooth driveability increase the efficiency of the engines.
Is It Possible to Increase Engine Torque?
In simpler words yes, the engine torque can be increased in a number of ways. However, it is a major modification in cars and can be subjected to a law breach. Therefore, before opting for any of the following torque-increasing options, consider the rules and regulations of your Emirate.
- Replacing Manifold and Fuel Injector: The manifold and fuel injector are essential for ideal engine exhaustion. Changing them at regular intervals can increase the air-to-fuel ratio and thus, impact the vehicle torque capacity.
- Adding Exhaust Header: The large exhaust header will exclude combusted air from the vehicle at a higher rate. This will help accelerate the process.
- Using Super or Turbo Charger: It is similar to the exhaust header, turbocharger will provide additional air to the engines leading to a more efficient combustion process.
- Regular Engine Maintenance: Regularly changing engine oil and other filters reduces friction and increases engine performance.
This was all about engine torque and its role in a vehicle. The internal combustion engines are designed to produce more torque and lesser speed. However, this can create a significant impact on fuel efficiency. On the contrary, the usage of electric current and magnetic fields in electric vehicles exempt this issue. If you are still driving an old vehicle with lower torque it is time to leverage from higher torque. Browse through these used cars for sale in the UAE and upgrade your vehicle.
