Preheater
The pre-heater is suitable for facilitate engine start at low temperatures environments environmental and contributes to a significant reduction wear parts of piston group. The heater consists of: • boiler with guide pipe; • electric spark ignition system; • fuel tank; • for electric fan; • electromagnetic shut-off valve; • control panel; • self-leveling funnel • pipes, connecting tubes and hoses; • drain tap. The boiler pre-heater is constantly connected with the engine cooling system. Side fuel fill- alleviating fuel appropriate to the engine type (gasoline or diesel fuel). Fuel flows by gravity into the combustion chamber of the boiler through the electromagnetic shut-off valve. The air required for combustion of the top Liwa, is served by an electric fan. Initial CL- ganie fuel mixture is performed by the glow plug, further burning from a previously lit flame. Hot gases heat the boiler, and then sent, are through the pipe on the sump for post-heating the engine oil. Due to convection the hot water enters the cooling jacket of the engine while cold you are tesnaya in the boiler. In vehicles with diesel engine body the heater is used at temperatures below -25°C. At a higher temperature is used electrovalence the device comprising a flare candle Naka- Libanius, in which the fuel evaporates. Fuel vapors CME- Sivitsa with air and ignited. Since facel- nye candle established in an inlet collector, the torch of th- education fuel warms up collectors 50 the air and this facilitates the cold start of the engine. After start if necessary, the driver may temporarily to support combustion of the flame, holding the button is enabled electrofocusing device. Otopitel the driver's cab of a freight vehicle Biel or interior of the bus and passenger car is the principle of using heat to the coolant engine. Hydronic systems are the same concept for all kinds of auto mobiles. The radiator heater is connected to the cooling jacket cylinder block (cylinder head) through the stopcock. The air heated from the radiator, served in vostokrustrade- inflammatory channel and further through the hoses to the nozzles, held at the feet of the driver, the windshield and in other months tah requiring heating. Adjustment income The heater of the driver's cab air in a radiator of a heater by a shutter, which has three positions. First position directed no air in the heater only from the cockpit (cabin), the second from the ventilation duct in the heater, and the third only in cabin with air intake from the outside. |
