Diesel Engine Questions and Answers

Frequently Asked Questions

1. What are the advantages of emei engine?

The engine is small in size, light in weight, large in power, fuel and energy saving.

There is white smoke from Engine 1015 of Emei. Why?

It is normal. In winter, due to the low ambient temperature, there will be varying degrees of white smoke when the diesel engine is started. After a while, as the temperature of the engine rises, the white smoke will gradually disappear

How is the oil channeling in the Emei water tank?

It should be oil radiator is bad, still have a kind of circumstance is cylinder cushion is washed out, former the amount of oil is bigger, and latter basically is accumulate carbon to enter cistern, very black and amount is lesser

How is it that the Emei engine can't start?

The engine does not start the main two points: 1 cylinder pressure is not enough;

There is something wrong with the fuel system.

If it is the water cooling machine of Emei, the fault should be in the fuel system (the single pump is more likely to wear out).

There is a lot of white smoke coming from the emei diesel engine. What is the problem?

The white smoke of the diesel engine can be found from two directions. The first reason is that water enters the combustion chamber of the engine. The cylinder pad is damaged.

Why does the crankshaft break during the use of Emei diesel engine?

The crankshaft in the normal use process, generally will not produce broken shaft, because the crankshaft in the design has been guaranteed to have enough strength, and to pass strict inspection and balance measurement.

Causes of crankshaft fracture are :

(1) the crankshaft has sand holes under the skin, loose;

(2) The physical properties, chemical properties and metallographic structure of crankshaft materials do not meet the requirements;

(3) The crankshaft breaks due to fatigue due to the long time overload of the engine;

(4) The main bearing nut is loose or the locking plate is not locked;

(5) The oil is too dirty, poor lubrication conditions, resulting in melting tile shaft fracture;

(6) When the crankshaft is repaired and worn with extra shingle, the crankshaft will break due to the failure of R Angle of the journal and the grinding to a right Angle.

(7) The main bearing cover is broken due to material or processing reasons;

(8) The power output end of the Emei diesel engine is not equipped with a clutch device. As a result, the crankshaft is subjected to the force perpendicular to the center line of the crankshaft and the back end of the crankshaft breaks due to fatigue.

Engine high temperature cold water air exhaust is not clean My Emei 1100 engine?

According to the phenomenon that you say basically can judge is blunt cylinder cushion, if do not want trouble, can measure cylinder head bolt tightening torque first to see, if small, try to tighten according to the regulation

Why does emei diesel emit black smoke?

There are many problems that cause smoke. The external factors include fuel, fuel filter, air filter, air inlet, and fuel injector. The high pressure oil pump needs to be validated.

When the Emei 1013 diesel engine is working, it suddenly runs unsteadily, the power drops, and the exhaust pipes emit blue and white smoke. What's the matter?

Please check whether the oil pipeline is blocked, breakage or leakage, joint work less or too loose mixture of carburetors, fuel pump, oil pump is out of order, wood filter blockage, compression, diesel fuel tank vent plug, engine overheating, valve stuck or run suffocate suffocate, valve block, valve spring damage, damage of piston ring, wear blue and white smoke coming or ablation engine cylinder liner shall be checked.

Why does emei diesel give off blue smoke?

The blue smoke is mainly caused by burning oil.

The reasons are as follows :(1) the piston and the cylinder liner are seriously worn, the clearance is too large, the oil enters the cylinder combustion;

(2) Improper assembly of piston rings results in matching;

(3) Severe wear of valve rod and valve guide;

(4) Piston ring oil ring damage or because of carbon accumulation more stuck, lost the function of oil scraping;

(5) Too much oil, et

The oil pressure indicator of Emei engine shows abnormality. How to solve it?

The engine oil pressure indicator is abnormal: fault determination: true fault.

Cause analysis: When the indicator indicates abnormal oil pressure, the engine component is at fault.

If the oil gauge pointer shows low pressure or the instrument pointer shows large fluctuation, it may be caused by the wear of the oil pump, the filter is blocked by dirt, the oil absorption filter is exposed to the oil level, the oil level is low, the air mixed in the oil path and the failure of the pressure gauge.

In addition, low viscosity of lubricating oil, oil seal and poor lubricity, too much viscosity of lubricating oil under cooling, too much oil sludge will also cause oil pressure indicator abnormal display.

What is the difference between EMei engine Water cooled and High-end ?

There is no difference between the two engines. The biggest difference is that the power high-end is stronger than 10%-15% normal water cooled ,others advantages will be send you if you are interested in, email us please.

What is the cause of the Emei engine mixed up ?

(1) Engine channeling divided into two, one is due to piston ring channeling, the other is the cylinder pad, cylinder block, cylinder head between the channeling.

(2) piston ring aeration is caused by too much wear between the cylinder liner and the piston ring, so that the tension of the piston ring is not close to the cylinder liner. Therefore, in the compression stroke of the engine, there is mixture “aeration” from the piston ring clearance to the crankcase.

(3) The damage to the engine is not very bad for this channeling.

(4) The second channeling is generally cylinder pad aging, the cylinder block and cylinder head corrosion caused by the sealing between the cylinder head and the cylinder block is not strict, resulting in the compressed gas channeling from the clearance to the cylinder head, the cooling channel around the cylinder block, oil channel.
