Abstract: PURPOSE:To detect leakage at an early stage with high accuracy by providing a temp. detector, a max. value selection circuit and a comparing circuit. CONSTITUTION:The atmospheric temps. at the respective places in a machinery chamber 2 are detected as signals (c) to (f) and the highest temp. signal in the machinery chamber 2 is selected by a max. value selection circuit 6 to be compared with a set value 8 by a comparing circuit 7.

Title: Fuel injection control device for two-cycle internal combustion engine
Inventor: TAKANO YUICHI
IPC: F02D41/02
Filed: 1990-07-10
Abstract: PURPOSE:To shorten engine starting time by providing a switching valve opening means for opening the switching valves of the air blast valves of two cylinders shifted by 180 deg. in the crank angle during a reference signal generating process. CONSTITUTION:Air is compressed in the combustion chamber 4 of either one of two cylinders shifted by 180 deg. in the crank angle. Accordingly, when the switching valve of the air blast valve 9 of this cylinder with air in the combustion chamber 4 being in the compressed state is opened, the compressed air in the combustion chamber 4 of this cylinder is pushed into a compressed air distribution chamber 20, and this compressed air pressure rises. With this rise of the compressed air pressure, compressed air from the air blast valve 9 of the other cylinder flows out, but pressure difference between the combustion chamber 4 of the other cylinder from which the compressed air flows out and the compressed air distribution chamber 20 is considerably smaller than the pressure difference between the combustion chamber 4 of the compressed cylinder and the compressed air distribution chamber 20. The compressed air quantity pushed into the compressed air distribution chamber 20 is thereby larger, so that the compressed air pressure in the compressed air distribution chamber 20 is boosted before the generation of a reference signal.
