Many car owners are always looking for maintenance workers to brush horsepower. The greater the horsepower, the greater the performance of the engine, and this is not the case!

They probably don't know the relationship, so they don't know how to explain the horsepower, torque, or displacement. They want to make sure their relationship is first understood……

horsepower

The horsepower of the engine in the northern part of Baotou refers to the output capacity of the engine (the work done), that is, the output power. The output power is the most important parameter to measure vehicle performance, which is used to measure engine performance. We often say that "this car is really interesting" is actually because the engine torque is strong; need larger output power (i.e. HP).

torque

The torque of the engine running in the northern part of Baotou is the torque that the engine outputs from the crankshaft end. The torque unit of nm (Nm). Under the condition of fixed power, it is inversely related to the engine speed. The faster the speed, the smaller the torque, the greater the reverse, which reflects the vehicle's load capacity in a certain range.

displacement

Baotou North running spare parts, engine displacement is the engine cylinder work volume of the total, single cylinder displacement Vh and cylinder number I product. While the cylinder working volume refers to the volume of gas piston from TDC to BDC swept, also known as single cylinder displacement, it depends on the bore and piston stroke.

Having made a distinction between these three concepts, let us look at the connection between the three.

"Horsepower and torque link

Horsepower and torque are equal to distance runners and lifters. Both represent the two characteristics of the car. The horsepower is mainly the efficiency of the work, and the torque is the explosive power of the truck.

Power (kW) = torque (N * m) * n (RPM) x, as if we use a wrench to screw, and if we wrench the greater the force, then the greater the torque the screw will suffer, and the less torque it will suffer.

"Not necessarily fuel-efficient small displacement

Many people have a misunderstanding, that is "small displacement of the car will be more fuel-efficient," in fact, the right is the best, if unreasonable choice of small displacement model, overload operation efficiency is slow, but will aggravate the wear and tear between parts. At the same time, in order to obtain greater horsepower and torque, speed rise, fuel consumption is certainly low.
