3 to 5 bar??? Not correct, common rail diesel engine has a maximum 1200-1500 bar. To start up the engine 200-250 bar and normal use can be varied between 300-500 bar depending on the brand of common rail diesel engine.

Ser at this engine how to set timing.. Sorry I wrote wrong about 40-45 degrees before TDC at Find Hansen's engine, should be between 45 and 55 degrees before TDC. His diesel engine is set at 45 degrees before TDC can set up to 55 degrees, but the lever with excenter at the fuel pump (see at...

Here is my work place, worked since 1993.. 😊

See in his website, there is well written about fuel: Kerosene--Petroleum, mixed with 2 % mineral two--stroke oil. And timing: The system enable the ignition timing to be changed about 15 crankshaft degrees with the lever, injection is set on a between 40-45 degree.

In fact the compression ratio is not same in large , medium and small diesel engine due pressure vs volume is difference in these engines. In the large ship engine compression ratio lower than mediun and small diesel engine.

Increase the compression ratio one step up and try until it is able to ignite the fuel of its own heat from compression. Find Hansen diesel engine has a compression ratio of 20: 1 and injection begins at 40-45. You must test how far the engine can inject before TDC without getting an ignition...

How big is the compression ratio in your engine? At higher compression ratio is developing higher temperature. If the high compression ratio is high enough, then there is the problem of good atomization of the fuel for the engine to be able to start up without heating the cylinder head. By...

Running the dieselengine with ether added in kerosene is not cheap fuel economy. It means the injector must atomize the fuel so very smaller drops to heat up quickly to ignite due ignition lagg (The time from the atomized fuel is leaving the injector to the fuel is ignited in the length of...

Correct...

I'm working at car shop. Most common to set all 3 piston ring gap 120 degree or 4 ring 180 degree degree ring gap when mount the piston into the cylinder with 2 rings in 45 degree off-set from 2 other rings, let us say the two rings 180 degree then next 45 degree off-set then 2 rings 180 degree...

Hehehe😄, Thommo.. Castor oil is a lubricant for the model engine. Also the model diesel engine with variable compression are running on kerosene/ether. Ether is a igniter for kerosene. 🙂

See in the post #16 to improve against to wear out the camshaft.

$300 It is a lot of money to produce an engine with cheap materials that do not keep the quality. The Chinese are one step ahead of buyers who buy an engine as they did not expect it to be a short-lived joy for buyers so the Chinese expect to sell even more engine at a good profit. And in...

You got about the same answer as here and the other forum when we talked about pump diameter and stroke of a certain size of cylinder volume in the engine. In fact, the stroke during operation at a certain speed is never a fixed stroke as it varies all the time in a range from the lowest to the...

As a communist would ask the buyer: What are you going to use high quality steel for? Maybe not everyone can buy high quality materials without permits in China. Here we had Soviet lathes and the day my former friend who worked in a machine shop ordered new gears because the old gears broke in...

Simply answer: Remnants of steel from the Chinese Cultural Revolution when people tried to produce steel from backyard foundries in their respective homes that must be used up without loss of income. ;)

I can't understand why the cam shaft was not made of hard steel to example drill rod/silver steel. Bad selected steel as material for cam shaft who are too soft to resist wear from valve lifter. And there is not rotating valve lifter affected by cam shaft to resist wear, also the centerline of...

In outlet, the spring must be strong (not stronger than injector needle spring), but weak spring in suction side due limited by force of vacuum created by pump.

Steamchick .. The cone and length varies from nozzle to nozzle depending on the type of diesel engine built as a direct injection, pre-chamber or vortex chamber diesel engine. Semi-diesel engine is injection nozzle difference from diesel engine injection nozzle as it is not high pressure that...

The pump stroke varies all the time depending on the speed and load so there is no fixed pump stroke in a diesel engine that it can go far down to the lowest pump stroke to the highest pump stroke in a speed range. If you load a motor, then it gives the larger pump stroke, you let it run...
