When to use low end torque and high end torque?

‘Low-End-Torque’ is the amount of torque that engine produces at the lower engine rpm band i.e. between 1000-2000 rpm. This rpm band is very crucial when moving a vehicle from stand-still or driving in slow-speed conditions such as in traffic.

What causes a car to lose power after 70K miles?

The MAF (Mass Air Flow) Sensor. A bad or going-bad MAF can cause the loss of power. These are usually good to 70K miles. A bad MAF sensor might produce a sudden reduction in car power, but the normal failure mode is a gradual loss of power over weeks.

What causes a car to lose power when driving up hills?

The muffler reduces the noise from the exhaust and the catalytic converter reduces the exhaust pollution. If either one of these filters gets clogged, it limits the engine’s power and ability to accelerate.

When does the torque reach its maximum value?

The HP reaches its maximum value later at a higher engine rpm and then fades out at the red-line. Most modern diesel engines deliver a ‘ flat-curve ’ torque. In ‘flat-curve’ design, the engine produces maximum torque at a ‘ lower-to-middle-end ’ of the engine speed i.e. approx. 1500 rpm onward.

What causes a loss of power in an engine?

2. Fuel Anything that restricts fuel from entering the cylinder will cause a loss of power if the engine requires more fuel than is injected. Clogged fuel injectors create a cascade of problems. Deposits can build up on the injectors over time from heat soak or poor fuel.

What causes a car to lose power when going uphill?

If your vehicle loses power under heavy acceleration, or traveling uphill, or sputters while maintaining a high speed, it could be the result of a worn out fuel pump. 3.

What causes an engine to lose compression over time?

There are several different ways an engine can lose compression: One of the major things that can happen over time is the piston rings will wear down, and this will allow for blow-by. Some of the high pressure air and fuel mixture combusting will pass by the pistons and travel along the cylinder walls into the crank case.

When does a car lose power while driving?

Here’s one of the most expression you often encountered in car loses power while driving situation. You often encounter this situation when suddenly running at an unusually high speed. The soot in the combustion chamber fell into the mouth of the valve so it could not be closed, the machine died suddenly.
