Diesel Generator Tech

Yuchai, famous China engine brand, is located in Yulin city, Guangxi Zhuang Autonomous region, China. MTU Yuchai Power, a joint venture set up between Rolls-Royce Power Systems and the Chinese diesel engine manufacturer Guangxi Yuchai Machinery Company, is preparing for the start of series production of MTU Series 4000 engines . On 9 April, in the presence of over 100 guests, Yan Ping, Chairman of Guangxi Yuchai Machinery Company, together with Andreas Schell, President of the Rolls-Royce Power Systems business unit, unveiled the first MTU Series 4000 engine manufactured in Yulin. Preparations for the completion of the assembly lines for high-volume series production are in full swing, with the large test bench required for engines with power outputs of up to 3,500 kW and as many as 20 cylinders currently being calibrated. “With the MTU Series 4000 engine, we have precisely the kind of product the market in China requires,” said Rolls-Royce Power Systems President Andre...

Volvo Engine Forced ventilation - engine compartment When a remote radiator is installed, consideration must be given to engine compartment ventilation. First of all, the exhaust system in the engine compartment must be efficiently insulated so that heat radiation is minimal. NOTICE! Because of the risk for overheating the exhaust manifold and turbocharger may not be insulated, only the exhaust pipe and silencer. The best forced ventilation systems normally comprise two electrically-driven fans. One fan forces air into the compartment and is installed on the wall directly opposite the generator end. The other fan extracts air hot air from the engine compartment. This fan must be installed on the wall next to and above the engine. An air duct is required on the inlet side if the cooling air does not reach the generator/engine. The ducting leads air to the generator and over the engine to the extraction fan. If no air ducting is installed when the inlet fan is located high up, in...

This article mainly introduces Volvo engine/diesel generator compartment ventilation. When an engine with an integral radiator is installed in an engine compartment the fundamental principal is to remove hot air from the compartment and, using minimal circulation, draw in air that has the same temperature as the ambient air outside the compartment. The illustration shows the most suitable engine location in relation to the structure's walls. The objective is to draw in cool air at the lowest possible point and expel it through the radiator and out of the structure. It is unsuitable to locate the engine so that the radiator is next to the opening in the wall. This would cause hot air to circulate back to the cooling fan through the gap between the radiator and the wall when the engine is running. This results in inefficient cooling and may cause overheating problems. The discharge opening in the wall must have a free flow aperture that is approximately 25 % greater than t...

Presentation EMS (Engine Management System) EMS is an electronic system with CAN communication (Controller Area Network) for diesel engine control. The system was developed by Volvo and includes fuel control and a diagnostic function. Summary The system comprises such items as a control unit, sensors and injectors. The sensors send input signals to the control unit, which in turn controls the injectors. The information from the sensors gives exact data about prevailing operating conditions and allows the processor in the control module to calculate the correct injection amount, injection timing and check engine health. Input signals The control unit receives input signals about engine operating conditions from the following components - coolant temperature sensor - charge air pressure and temperature sensor - rpm sensor, camshaft - rpm sensor, flywheel - coolant level sensor - oil pressure sensor - fuel pressure sensor ...
