How to increase the power of a diesel engine

The idea to create a powerful engine is attractive to many car owners. A powerful motor allows you to quickly pick up speed and join the overall flow. At any time, if necessary, it is easy to make a dynamic maneuver and leave behind a more expensive foreign car. Such moments give a lot of incomparable sensations.

Tuning the engine helps to achieve a significant increase in the dynamics of the car. If you competently approach this task, it will turn out to reveal the full potential of the motor. This article will discuss how to increase the power of a diesel engine. The described methods help to improve the power unit and achieve a real result. But before you start tuning, learn the principles of diesel engines.

How a diesel engine works

Fuel mixture. A feature of the diesel engine is the method of formation and ignition of the mixture. First, air enters the cylinder, and then the piston compresses it. At a certain point, fuel is injected through the nozzle. From the high temperature of the compressed air, it ignites in the cylinder.

Supply system. This is the main link in a diesel engine, which provides the necessary portion of fuel to the combustion chamber at a precisely defined moment and with the right pressure. The power system is of two types: mechanical and electronic.

Mechanical equipped with old engines. A feature of this system is the high pressure fuel pump, which pumps fuel to the nozzles. The power of injection depends on the speed of the crankshaft. Some of the described tuning methods are not suitable for such engines.

Modern cars are equipped with an electronic power system. Fuel is pumped into the ramp using fuel injection pump, and then injected with electromagnetic nozzles. The dosage, pressure and moment of injection are controlled by an electronic control unit. By changing its work, you can easily improve engine dynamics. It is these motors that are suitable for tuning.

How to increase the power of a diesel engine

The increase in power depends on the quality of combustion of the mixture. High pressure and regulated injection help the fuel burn completely and release maximum useful energy. Thanks to the balance between the amount of air and fuel, it is possible to significantly increase the power characteristics of the motor.

Tuners of diesel engines have several options for improving dynamics: chip tuning, installing a power increase module, turbocharging.

Chip tuning
The easiest way to increase engine power. This method consists in changing the settings of the computer. Such a procedure should be carried out by a specialist who has the necessary technical tools and special software for work.

How is the increase in dynamics? The electronic fuel supply system is controlled by the computer. This unit contains a microprocessor that controls the volume of air, injection, crankshaft speed. The computer interacts with various sensors, receiving information about the state of the engine. Given the data, changes the operating mode of the power unit. Re-flashing the control unit helps improve dynamics.

Advantages:

• fuel consumption is reduced;
• increases the dynamics of the motor;
• the maximum speed limit is removed;
• failure in the internal combustion engine disappears after pressing the gas pedal.

Disadvantages:

• changing the settings will void the warranty if the car is new;
• The procedure for flashing the computer is associated with risk - the consequences are not reversible.

Power Modules
They are popular means of increasing the power characteristics of a diesel engine. These are special modules that interact with the fuel supply system. They do not interfere with the operation of the computer, and in parallel with it control various electronic sensors. The installation procedure is simple, just follow the attached instructions.

There are four types of modules

1. Module for changing injector control pulses. Controls the activity of the nozzles - slows down or delays the raising of the needle. As a result, the ignition timing changes, the efficiency of fuel combustion increases, and the consumption decreases. The module is connected to the nozzle wires. Suitable for any diesel engine with a modern fuel supply system.
2. Module for changing the operating mode of the injection pump. Interacts with a fuel pressure sensor. Receives information from him and understates the testimony. As a result, the pressure in the pump increases. This allows you to increase the dynamics of the engine without compromising the resource. The module is connected to the high pressure fuel pump and ECU wires. Approaches diesel engines with a mechanical fuel supply system, released before 2008.
3. The module for changing the readings of the fuel rail pressure sensor. Deceives the computer, informing him of a decrease in pressure in the fuel rail. As a result, the control unit thinks that the engine dynamics has fallen and decides to change the intensity of the nozzles. This reduces consumption, and increases power. The module is connected to the wires of the ramp pressure sensor. Suitable for engines with a modern fuel supply system.
4. Module for optimizing the operating modes of the central processor of the computer. Determines the pressure of the fuel system. If it increases, sends a signal to the computer to increase the timing of the injectors. The built-in program corrects the engine without the help of the computer. It does not underestimate the readings of the sensors. The module is integrated in a high pressure system. Suitable for all modern diesel engines.

Advantages of modules:

• increase engine power;
• reduce fuel consumption;
• Install quickly and easily.

The disadvantages of the modules:

• reduce the resource of the cylinder block;
• reduce the service life of injection pump and nozzles;
• increase the emission of harmful substances.

Turbocharging
Turbine significantly increases engine power. It pumps a lot of air into the cylinder, and the electronic system increases the amount of fuel supplied. The exhaust stream spins the turbine at low engine speeds. Thanks to this, turbo lags disappear. The thrust of the motor increases from the bottom.

Diesel engines have a feature - the lack of a throttle. Therefore, air is quickly pumped into the cylinders, without the help of complex turbine control systems. In order not to overheat the engine, they put an intercooler. This device cools the air pumped into the cylinder.

Advantages:

• efficiently burns the fuel mixture;
• significantly increases engine power.

Disadvantages:

• short service life;
• increased fuel consumption;
• high cost of high-quality turbine;
• mandatory use of expensive oil and high octane fuel.

The described methods for increasing the power of a diesel engine will help to make the car fast. The easiest way is to install additional modules. But remember that by increasing the dynamics of the engine, reduce its resource. In addition, a fast ride will require additional costs. You will have to spend money on installing reliable brakes. Before tuning the engine, first think carefully about whether you really need this power.
