Baotou North Benz accessories WD615 three (EGR) series diesel can fully meet the requirements of heavy truck power and engineering machinery etc. requirements, the diesel engine series 2 diesel engine in Europe based on the increase of EGR control device, the electronic controlled fuel injection pump fuel supply rate, and euro two is connected with the basic agreement the vehicle, only the thermostat outlet change slightly, compact structure, good rigidity, reliable work, long service life, excellent performance, good economy.
ECU is the core of the engine electronic control system, all the controls are realized by ECU. ECU according to the engine speed, load, inlet temperature, cooling water temperature and pressure signal, control valve to open EGR, a small part of the waste exhaust valve to the exhaust system by EGR, and the mixed gas mixture into the cylinder in combustion.
When the engine is at idle speed, low speed, small load and cooler, exhaust gas recirculation (ECU control does not participate in the RGR valve closed), avoid the engine performance is affected; when the engine speed, and more than a certain load reaches a certain temperature, the ECU control part of the waste recycling in less (as well as EGR valve opening).
Baotou North Benz accessories water temperature sensor used to measure engine cooling water temperature.
The intake temperature and pressure sensor is installed on the intake pipe to measure the intake temperature and pressure.
The pre stroke sensor is installed on the stepping motor of the fuel injection pump, and the pre stroke is detected, and the feedback signal of the ECU control stepping motor is transmitted to the ECU.
The throttle position sensor is installed near the accelerator rod of the fuel injection pump, and the position of the throttle pull rod is detected.
Baotou North Benz parts crankshaft speed sensor installed on the flywheel housing, used to measure the engine speed.
Double cylinder air compressor:
Double cylinder air compressor by injection pump gear, lubrication: lubricating oil from the main oil channel through a tube is fixed on a cylinder body into the air compressor lubricating oil through the bearing, and then back to the gear chamber to the oil pan.
Double cylinder air compressor air entrance is through the air filter, air passes through the air filter, into the supercharger before a branch to the double cylinder air compressor.
Double cylinder air compressor cooling from cylinder connected pipe to double cylinder air compressor cylinder head, cylinder head by water after receiving the diesel engine pump inlet side.
Double cylinder air compressor and engine transmission ratio is 0.5, no need to install the transmission shaft, the installation should pay attention to the timing of the injection pump. Before installing the fuel injection pump gear, the other gear of the engine must be in the position of the required oil supply angle, the position of the air compressor crankshaft must be in the correct position according to the following figure, then the oil pump gear can be installed.
