摘要： PURPOSE:To shorten a time before reaching initial explosion and to reduce generation of white smoke by efficiently increasing a temperature of air sucked into a cylinder while increasing a rotational speed of a crankshaft by reducing pumping resistance when started a diesel engine. CONSTITUTION:Air, closely sealed between the inside of a cylinder 1c and the inside of an exhaust manifold 11 in the upstream from an exhaust brake valve 5 connected to this cylinder, is continuously compressed and expanded by reciprocating a piston 8, and in this way, a temperature of air in the cylinder 1c is increased, to inject fuel into the cylinder 1c first when this air temperature sufficiently rises, so that a diesel engine 1 is started.

摘要： PURPOSE:To provide a two-stroke engine which can prevent a back flow of the suction air to a scavenging port, and can increase the pressure in a cylinder at the termination of a compression stroke so as to improve the starting property. CONSTITUTION:When the passage area of an exhaust pipe 15 is throttled by an exhaust throttle valve 7, a control valve 9 is opened only for a specific period immediately before the finishing of an exhaust stroke, the exhaust gas in a cylinder 8 is accumulated in a surge tank through an exhaust passage 5, the pressure in the cylinder is reduced, a back flow of the suction air is prevented, and the volume efficiency is improved. And the control valve 9 is opened only for a specific period immediately after the starting of the compression stroke, a high temperature exhaust gas is fed from the surge tank 4 into the cylinder 8, the pressure in the cylinder is increased so as to increase the pressure in the cylinder at the termination of the compression stroke, and the starting property is improved.

摘要： PURPOSE:To provide a fuel heating control method for a flexible fuel vehicle engine, by which stable combustion can be attained and the power consumption can be limited to the minimum. CONSTITUTION:According to the alcohol concentration, a warming up mid-way decision value T1 and a warming up completion decision value T2 are set in S114 S115, and if the cooling water temperature Tw is lower than a warming up mid-way decision value T1 in S116, a port heater unit is put in its heating state. If the cooling water temperature Tw is higher than the warming completion decision value T2 in S117, the port heater unit is put in its non-heating state. Further, if the cooling water temperature Tw is above the warming up mid-way decision value T1 and below the warming up completion decision value T2 in S118, the port heater unit is put in the heating state in the idling state, and the port heater unit is put in the non-heating state in the non-idling state.

摘要： PURPOSE:To prevent engine strike and hunting and to improve stability by thinning out fuel injection for each cylinder for every set cycle at the time of a high rotation high load driving state of an engine within set time after starting or within set temperature at the time when a cold state of the engine is discriminated at the time of starting the engine. CONSTITUTION:In a control device 51, to an input port of an I/O interface 56, various kinds of sensors 22, 41-43, 45, 46, 48, 50 and others to respectively detect driving states of an engine are connected. In the meantime, to an output port, an injector 23, a PTC heater 33d is oppositely provided in the fuel injection direction of the injector 23 and others are connected. In this case, the control device 51 discriminates whether the engine is in a cold state or not at the time of starting the engine. Additionally, at the time when it is in the cold state, the control device 51 measures elapsed time after starting or computes a temperature rising amount. Furthermore, within set time after starting or within set temperature, whether the engine is in a high rotation high load driving state or not is discriminated. Additionally, at the time when the engine is in the high rotation high load driving state, fuel injection is thinned out for each cylinder for every set cycle.

摘要： PURPOSE:To prevent droplet of fuel without lowering the life of a battery by carrying out heating control and cranking control against a fuel heating means in accordance with alcohol density in fuel and engine temperature. CONSTITUTION:A means to judge whether it is possible to start or not in accordance with alcohol density in fuel and engine temperature and a process to carry out cranking after heating and warming a fuel heating means 23d provided in the fuel injection direction of an injector 24 in the case when it is judged impossible to start are furnished. Additionally, a process to carry out cranking simultaneously when the fuel heating means 23d is heated in the case when it is judged possible to start and engine temperature is lower than fuel vaporizable temperature and a process to carry out cranking of the fuel heating means 23d in the non-heating state in the case when engine temperature is higher than the fuel vaporizable temperature are furnished. Consequently, it is possible to reduce burden of a battery at the time of starting and to acquire favourable starting performanceby way of preventing droplet of fuel.
