IPC: F01P3/20
Filed: 1987-12-17
Abstract: PURPOSE:To prevent white smoke in exhaust gas at the time of starting from occurring by setting a specified temperature to a specific value, in a device which makes an engine body rise up to the specified temperature with cooling water heated at the starting. CONSTITUTION:Cooling water 3 is filled up in a water jacket formed in a cylinder head 1 of an engine, and this cooling water is circulated in an interval with a heating part provided with a hot insulation heater 5 at the time of engine starting and it is heated, whereby an engine body 2A is made so as to up its temperature. When temperature in the engine body 2A comes to the specified one, a thermometal cut-out 6 is opened by output of a temperature sensor 4, and current-energization to the hot insulation heater 5 is controlled so as to interrupt it. In this case, the temperature is specified to a temperature of more than 50 deg.C, and thereby fuel is made so as to attain a complete combustion at the starting, and thus white smoke in exhaust gas at the starting is prevented from occurring.
