How to increase the power of a diesel engine

The idea to create a powerful engine is attractive to many car owners. A strong 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.

Engine tuning helps to achieve a significant increase in the dynamics of the car. If you correctly 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 to achieve a real result. But before proceeding with tuning, learn the principles of operation of diesel engines.

How does a diesel engine work

Fuel mixture. A feature of the diesel engine is a method of formation and ignition of the mixture.At 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 that delivers the necessary portion of fuel to the combustion chamber at exactly the right moment and at the right pressure. The power supply system is of two types: mechanical and electronic.

Mechanically equipped with old models of engines. A feature of this system is the injection pump, fuel injection to the injectors. Power injection depends on the frequency of rotation of the crankshaft. Some of the described tuning methods are not suitable for such engines.

Modern cars are equipped with electronic power system. Fuel is pumped into the ramp with the help of injection pump, and then injected with electromagnetic nozzles. The dosage, pressure and injection timing are controlled by an electronic control unit. Changing his work, you can easily improve the dynamics of the engine. Such motors are suitable for tuning.

How to increase the power of a diesel engine

The increase in power depends on the quality of the combustion mixture. High pressure and regulated injection help the fuel to burn completely and to release the maximum of 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.

The tuners of diesel engines have several options for improving the dynamics: chip tuning, installation of a module to increase power, turbocharging.

Chip tuning
The easiest way to increase engine power. This method is to change the ECU settings. Such a procedure should be carried out by a specialist who has the necessary technical tools and special software.

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

Advantages:

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

Disadvantages:

• change of settings leads to loss of warranty if the car is new;
• The procedure for reflashing the computer is associated with risk - the consequences are not reversible.

Power Upgrade 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 work of the ECU, and in parallel with it control various electronic sensors. The installation procedure is simple, just follow the nested instructions.

There are four types of modules.

1. The module changes the pulse control nozzles. Controls the activity of the nozzles - slows or delays the lifting of the needle. As a result, the ignition timing changes, the efficiency of fuel combustion increases, and consumption decreases. The module is connected to the injector wires. Suitable for any diesel engines with modern fuel supply system.
2. The module changes the operating mode of the pump.It interacts with the fuel pressure sensor. Receives information from him and underestimates. 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 wires of the injection pump and the computer. Suitable for diesel engines with a mechanical fuel supply system, produced before 2008.
3. The module changes the readings of the fuel rail pressure sensor. Cheats the computer, telling him about the pressure drop in the fuel rail. As a result, the control unit thinks that the dynamics of the engine has dropped and decides to change the intensity of the injectors. This reduces consumption and increases power. The module is connected to the ramp pressure sensor wires. Suitable for engines with modern fuel supply.
4. Module optimization modes of the central processor of the ECU. Determines the pressure of the fuel system. If it increases, it sends a signal to the computer to increase the timing of the injectors. The built-in program corrects the operation of the engine without the help of an ECU. Does not underestimate sensor readings. The module is built into the high pressure system. Suitable for all modern diesel engines.

Advantages of the modules:

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

Module disadvantages:

• reduce the life of the cylinder block;
• reduce the life of the pump and injectors;
• increase the emission of harmful substances.

Turbocharging
Turbine, significantly increases the power of the engine. It pumps a lot of air into the cylinder, and the electronic system increases the amount of fuel supplied. Exhaust gas flow 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 - no choke. Therefore, air is rapidly injected into the cylinders, without the help of complex turbine control systems. In order not to overheat the engine put intercooler. This device cools the air injected into the cylinder.

Advantages:

• effectively 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 to increase the power of the diesel engine will help 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, fast driving 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.
