Abstract

The invention relates to a gas turbine engine. An oil pump (1) of the gas turbine engine is equipped with an oil pump turbine (2), and exhaust gas discharged from the gas turbine engine drives the oilpump (1) via the oil pump turbine (2). The oil pump turbine of the invention is connected with the oil pump in the whole course, so action time is longer; a precise logic can also be set, oil pressure is controlled by an ECU, and a bypass is arranged for pressure relief, so control precision is higher. In addition, a motor is driven while the oil pump turbine is driven; and at the time, the motorhas a power generation function and can charge a storage battery, so kinetic energy in the exhaust gas of the engine can be more fully utilized.

Description

technical field [0001] The invention relates to a gas turbine engine. More specifically, it relates to a gas turbine engine that utilizes energy in exhaust gases to drive an oil pump. Background technique [0002] As we all know, the exhaust gas discharged from the engine has great mechanical energy and thermal energy, most of which have not been fully utilized. In order to utilize the above-mentioned mechanical energy and thermal energy, turbocharged engines have been widely used. However, a large portion of the kinetic energy in the exhaust gases from a turbocharged engine remains unused. [0003] Specifically, the turbocharged engine has its turbine in a non-working state under some operating conditions. When the turbine is not working, the exhaust valve is in the open position. At this time, the exhaust gas from the engine does not work on the turbine, but directly enters the exhaust pipe. Therefore, most of the energy of the exhaust gas is not utilized. Under high...
