Diesel engine is a engine that burns diesel to obtain energy release.It was invented by German inventor Rudolf Diesel in 1892. To commemorate the inventor, diesel is represented by his surname Diesel, and the diesel engine is also known as the Diser engine (Diesel Engine).
Diesel engine structure
Stranging link mechanism: The body components -cylinder body, cylinder head, cylinder sleeve, spherling bearings, main axle cover and other main movement components -crankshafts, connecting rods, pistons, pistons, flywheels, belt wheels and other fuel systems -fuel tanksA gas distribution mechanism such as oil pump, oil filter, oil and water separator, fuel injection pump, fuel injection mouth, etc. — —— 、 、 、 timing gear, camshaft, follow -up arm, pushing rod, rocker arm, intake valve, intake valve,排气门、气门弹簧、气门导套、气门锁销、空气滤清器、涡轮增压器、消音器、中冷器等润滑系统——油底壳、油泵、油冷器、滤油器、Pistons cooling systems and other cooling systems -electric appliance systems such as radiator, water pump, fan, thermometer, etc. -batteries, generators, start motors, start switches, battery relay and other diesel engines have basically the same structure as gasoline engines, all have the same structure, all have all, all have all, all have all, all have all, all have all, all have all, all have all, all have all, all have all, all have all, all have all, all have all, all have all, all have all, all have all, all have all, all have all, all have all, all have all, all have all, all have all, all have all, all have all, all have all, all have all, all have all, all have all, all have all, all have all, all have all, all have all, all have all, all have all.Cylinder body, cylinder head, piston, valve, crank, crankshaft, camshaft, flywheel, etc.However, the former uses pressure -burning diesel, and the latter works with ignition gasoline. One "ignite" and one "ignite" is the fundamental difference between the two.The fuel of the gasoline engine enters the cylinder after mixing with the air in the air. And then ignited by the spark plug; the fuel of the diesel engine is sprayed into the cylinder directly when the compression itinerary is approaching the end, and the compressed air is compressed.This difference has caused its own characteristics of the structure of diesel engines in the fuel supply system.The fuel injection system of diesel engine is composed of fuel injection pumps, fuel injectors, high -pressure oil pipes and some subsidiaries.

Diesel engine with black smoke
The basic reason for diesel engines with black smoke is: insufficient fuel burning and incomplete.As a result, there are many factors that lead to the incomplete and incomplete factors of the diesel engine fuel. The main factors are as follows: 1. Factors in the fuel supply system: (1) Incorrect oil jet mouth oil, poor atomization or insufficient fuel injection pressure; (2) the fuel injection pump columnThe stuffing and oil outlet valves are worn, and there are insufficient pressure or too much oil supply;2. Factors in the combustion system: (1) The valve clearance is not correct; (2) the piston ring and the cylinder set are seriously worn, resulting in insufficient compression pressure; (3) Improper adjustment of the piston top gap, and the compression ratio is too small.3. Structural factors: (1) Inlet pipe or air filtration is not smooth; (2) The exhaust port is blocked and the exhaust is not smooth.4. Other factors: (1) The environmental temperature is too high; (2) the quality of diesel is too poor.

Diesel engine repair
4.3 Maintenance and maintenance of diesel generators 4.3.1 When maintenance and maintenance, pay attention to the relative position and order of demolition parts (marked if necessary), the structural characteristics of non -demolition parts, and master the force when re -loading back.(Use a torque wrench).4.3.2 The maintenance cycle of the air filter is performed every 50 hours of operation: A) Air filter display: When the displayed part appears red, it means that the air filter has reached the limit of use, and it should be cleaned or immediately cleaned or cleaned immediately.Replacement, process, light press the display at the top of the display to reset the display; b) the air filter: —— Remove the iron ring, remove the dust collector and filter element, and carefully clean the filter element from top to bottom; —— Filter element is not too muchWhen dirty, you can directly use the compressed air to blow, but you should pay attention to the air pressure should not be too large, and the spraying nozzle should not be too close to the filter element; -If the filter element is too dirty, the application of special cleaning solution purchased from the agent office is cleaned, and it is used after the completion.Electric heating fans are blowing dry (be careful not to heat); —— After cleaning, check should be performed. The method of inspection is to use light bulbs from the inside out and observe outside the filter element.The filter element of the same model should be replaced; ——It if the light spot appears, it should indicate the perforation of the filter element. At this time, the air filter should be installed carefully.4.3.3 The maintenance cycle of the battery is performed every 50 hours of operation: A) Check whether the battery is sufficient with electrical appliances, otherwise it should be charged; b) Check whether the battery liquid level is about 15mm on the polar plate.By the above position; C) Check whether the battery stream column is corroded or there is a trace of fire, otherwise it should be repaired or replaced, and butter should be applied.
