The power of the car engine - how to increase?

If we talk about the power of the engine of the vehicle, it is first necessary to be clear about what will be discussed. This work, which is produced during the combustion of the fuel-air mixture in the cylinder over a period of time. Is impossible to measure in the cylinders. Because manufacturers use some tricks: measured torque at the flywheel of the engine or with hydraulic brakes is to measure how large the amount of heat or electricity produced by the engine to calculate the effective power.

The engine Power output there are two types: gross and net. You should consider each of them separately.

Net measure on the engine, which is equipped with all the units and auxiliary systems, i.e. power steering pump, generator, intake and exhaust system, AC compressor, control system and security etc. This is the real power. It will be displayed in the vehicle.

Gross measured on the engine that is installed on the stand without any auxiliary equipment and systems. This engine power of the car is called lab or bench. And it is about 10-20 percent higher than the net.

We Need to realize that in the end the machine is driven by rotation of the drive wheels, not the engine directly. This tractive power. It is below net 3-10 per cent due to losses in transmissions for passenger cars and 20 percent – truck. The power of the engine of the vehicle is expended to overcome the two main resistance forces – the roll and a counter air flow. Another name – the aerodynamic resistance.

How to increase engine power? For this there are two ways.

The First – to increase its capacity, using high-quality motor oil, fuel and anti-friction additives. Still need to make changes in the very design of the engine. Consequences – increased fuel consumption.

The Second – to reduce the impact on the car of the resistance forces, resorting to reducing car weight, high quality wheels and tyres, upgrade suspension and transmission, to improve aerodynamic performance.

This shows that to increase the engine power is not so difficult, but the effort and funds necessary to put.

Before you make any changes to the car, it is worth considering that the increased power in most cases is directly proportional to the amount of fuel that the vehicle consumes. We should also consider the fact that in each model of machine, the capacity increase can be different. Because the engine of each vehicle is arranged in its own way. Work to increase the power should be entrusted to highly qualified specialists. After all, if people in autodele a rookie, and if he do something wrong – the motor will respond to this damage. However, if you have the willingness to take risks, then you need to remember – power increase can be achieved by increasing the volume of filled cylinders and go to fuel of the highest class.
