Direct Injection Diesel Generator VS Electronic Injection Diesel Generator

Diesel generator sets are divided into direct injection diesel generator sets and electronic injection diesel generator sets due to the different fuel injection methods of their engines. I believe that many users will have questions about the difference between the two when they purchase them, and which is better?

The direct injection diesel generator set is assembled from the direct injection engine. The direct injection engine is a traditional engine. Its fuel injection to the system (that is, the system fuel supply) only depends on the pressure generated by the engine on the fuel system when operating under different conditions, so it is easy to cause that it cannot accurately supply the required fuel according to the different conditions, affecting the normal operation and service life of diesel generator set.

The electronic injection diesel generator is composed of electronic injection engines. The electronic injection diesel engine precisely utilizes modern computer control technology, which can effectively use sensor detection technology (sensors) to detect the working status of the engine under different working conditions, such as pressure, temperature, intake volume, etc., and pre-set the most reasonable system working pressure and required fuel in the computer for different working conditions. The computer can monitor various data of engine operation in real-time under different working conditions, accurately supply fuel according to different working conditions, and ensure that the system's fuel supply no longer depends on the system pressure, but on the fuel supply time, which is the electrical pulse that the computer connects to the fuel injector based on the engine working conditions determined by the monitoring data, (In the electronic injection diesel engine, the opening of the fuel injector is not like the traditional pressure opening, but becomes an electromagnetic type fuel injector. It is opened by electromagnetic force.) This achieves the effect of noise reduction and fuel saving, and also extends the service life of diesel generator set.

Different properties of direct injection diesel generator in electronic injection diesel generator

1.  Direct injection diesel generator: A technology that directly injects fuel into the cylinder and mixes it with the intake air. It directly presses diesel fuel into the high-temperature and high-pressure cylinder body, causing it to self ignite and pushing the piston to move, thus achieving the working operation of the engine. Compared to electronic injection engines, direct injection engines consume more fuel, have higher noise, insufficient combustion, and have higher exhaust emissions.

2. Electronic injection diesel generator: A diesel engine that uses electronic control of fuel injection and emissions is called an electronic injection diesel engine. The electronic control will calculate and control the required fuel injection quantity and timing for each cylinder of the engine based on the diesel engine status signal, injecting diesel into the cylinder block through the injector under a certain pressure for atomization. And mixed with the incoming air flow, it enters the combustion chamber for combustion, ensuring that the engine and catalytic converter always operate in optimal condition, but requiring more frequent replacement of spark plugs and other components.

What are different advantages of direct injection diesel generator with electronic injection diesel generator?

1. Direct injection diesel generator: Low fuel consumption, high power output, compression ratio up to 12, and a 10% increase in power and torque compared to regular engines of the same displacement.

2. Electronic injection diesel generator: It minimizes the vibration and noise of diesel engine models, while further reducing fuel consumption and making emissions cleaner.
