Engine power - the history and practical advice

With the advent of the internal combustion engine to manufacturers, the question arose as to increase the engine power. The first motors were constructed very inefficient. Almost all parts were made of steel or cast iron, making the mechanisms of heavy, inert and short-lived. For example, in the mid-20th century automobile engine of 100 horsepower weighing almost half a ton. For comparison, in modern cars the engine of the same capacity weighs less than 150 kg.

To achieve this, manufacturers first improved the mechanical component of the engine: picking materials, alloys, developed and implemented technological innovations, which were embodied the latest achievements of metallurgy and chemistry. For example, the use of aluminum pistons have been able to increase engine power by more than 20 percent due to reduced weight and friction. Note that aluminium in pure form or in the car is not used, and apply its alloys with magnesium, silicon, manganese and chromium.

Improvements to the fuel system and the ignition system has also substantially increase the engine power. The surface type carburetor was replaced by the float, which was at first single, then multi. And then came the era of fuel injection systems that have come a long way from mechanical monoinjection to modern multipoint system of direct fuel injection.

Along the way and improved ignition system from the simplest of circuit breaker to electronic microprocessors. None of the modern engine without electronic control systems that take into account all the parameters relating to engine operation – temperature and air density, vehicle speed, throttle position, crankshaft, camshaft, chemical composition of exhaust gases, etc. as a result of processing the received data, the electronic system determines the optimal amount of fuel that should apply to the engine, and the moment of ignition of the fuel-air mixture. Thus, we achieve the most efficient operation of the gasoline engine.

Oil consumption in the engine. Six reasons

It is Hardly possible to find a motorist who would not be worried about the increased oil consumption. It is especially annoying when it happens with another new motor. Here are the most common causes that result in the consumption of oil in the engi...

The power Increase of the diesel engine is most often achieved by using a turbocharger, which pumps more air into the cylinder by the energy of exhaust gases. Also to improve the efficiency of fuel combustion in the modern diesel engines used a system called "Common Rail".

There are many ways to boost the power of the internal combustion engine. But we should not forget that intervention in the motor design – this is not only quite complex and time-consuming process, but very expensive. Need high-precision machines, special alloys and materials. Obviously, not all motorists will be able to spend on the crossing of the engine an amount comparable to half the cost of the car.

What can be done to the engine power always remained on top?

First of all, you need to verify that all factory adjustments were normal. The oil used in the engine must comply with the viscosity and qualification.

To reduce losses in the air intake it is recommended to use filters of zero resistance – so-called “my best" - good, now there is a huge selection of such filters. They can vary in shape, size, installation methods, recommended engine size. Due to the fact that filter manufacturers produce adapters for the most common types of engines, the installation of such a filter will not require significant effort and expense.

The Increase in engine power also depends directly on modernization of the exhaust system. Be aware that if your car is not a finished system, it is best to call the service station that spetsializiruyutsya on the exhaust systems.
