Abstract
The utility model relates to a field of diesel engine, in particular to a preheating device of intercooled turbocharged diesel engine, which comprises a water temperature sensor, a preheating control module, a preheating relay, and a glow plug, wherein the water temperature sensor is arranged in the cooling system of engine, the glow plug is arranged at fuel ejector or gas inlet manifold in the cylinder of engine, according to the cooled liquid temperature signal inputted by the water temperature sensor, the preheating control module determines whether the preheating relay is sucked or not so as to open the glow plug for heating. The utility model solves technical problem that the prior diesel engine can not be started at low temperature, thereby ensuring the engine can be started normally at low temperature, saving fuel and reducing tail gas emission during starting process.
Description
Technical field
The utility model relates to a kind of charge inter cooling diesel engine Preheating unit, the Preheating unit of the charge inter cooling diesel engine that a kind of specifically air displacement is 2.8L.
Background technique
The need of work certain temperature condition of motor car engine-petrol engine and diesel engine, cross when low in temperature, motor can't normal ignition, so in cold environment, automobile Chang Wufa normally starts, promptly allow under cryogenic conditions starting reluctantly, the exhaust emissions in the start-up course increases during also than proper functioning greatly, constantly wastes oil plant and has also polluted environment.In order to adapt to each regional weather, guarantee that motor also can normal starting under cryogenic conditions, the discharging when reducing engine start improves the cold starting performance of motor, need be the engine configurations pre-heating system.
The model utility content
The technical problems to be solved in the utility model provides a kind of height according to engine coolant temperature and determines whether motor is carried out preheating automatically, guarantees the charge inter cooling diesel engine Preheating unit that motor normally starts at low temperatures.
The technological scheme that the utility model adopted is:
Charge inter cooling diesel engine Preheating unit comprises cooling-water temperature sensor, pre-thermal control module, preheating relay, glow plug.Cooling-water temperature sensor is installed in the engine-cooling system, and glow plug is installed in motor in-cylinder injector place or the inlet manifold, and cooling-water temperature sensor output connects pre-thermal control module, and pre-thermal control module output connects glow plug by preheating relay.
Also comprise the pre-thermal light that is connected with pre-thermal control module in the said apparatus.
The good effect that the utility model had is: according to the height of engine coolant temperature automatically decision whether how long motor is carried out preheating and preheating, guarantee that motor normally starts at low temperatures, exhaust emissions amount when reducing engine start is saved oil plant, reduces and pollutes.
Description of drawings
Fig. 1 is the utility model schematic diagram
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
The utility model is in order to improve the preheat starting system that charge inter cooling diesel engine starting performance is an engine configurations, is example with 2.8L charge inter cooling diesel engine only below.Its basic functional principle is when coolant temperature 〉=20 ℃, does not need preheating before the engine start; And when coolant temperature＜20 ℃, just must preheating before the engine start.The length of preheat time changes with the height of coolant temperature.
As shown in Figure 1, charge inter cooling diesel engine Preheating unit comprises cooling-water temperature sensor 1, pre-thermal control module 2, preheating relay 3, glow plug 4.Cooling-water temperature sensor 1 is installed in the engine-cooling system, and glow plug 4 is installed in motor in-cylinder injector place or the inlet manifold, and cooling-water temperature sensor 1 output connects pre-heat control 2 modules, and pre-thermal control module 2 outputs connect glow plug 4 by preheating relay 3.Described device also comprises the pre-thermal light 5 that is connected with pre-thermal control module.
Cooling-water temperature sensor 1 passes to pre-thermal control module 2 with the temperature signal of engine coolant, and pre-thermal control module just determines whether carry out preheating according to temperature.Critical temperature can be set at 20 ℃ or other temperature as required, and also can set heating time.Being set at 20 ℃ with critical temperature is example, if the coolant temperature that measures is higher than 20 ℃, and pre-thermal control module decision not carrying out preheating.If measured temperature is lower than 20 ℃, pre-thermal control module decision carrying out preheating makes glow plug 4 energisings, heating preset time by preheating relay 3 actions.
The setting scheme of determining heating time according to water temperature is as shown in the table.
