As you know, the piston in the Diesel engine compresses the air in the cylinder so that it gets extremely hot. Fuel is then injected directly into the cylinder where it ignites and causes the power stroke. Because the Diesel engine operates at very high compression ratios it has to be very strong, and therefore heavy. The injector that squirts fuel into the cylinder has to be both strong and very precise in order to force a precise amount of fuel into the cylinder.
For these reasons, Diesel engines tend to be heavier than petrol engines, and more expensive because of the very precise engineering required in manufacturing the injectors. So they are not practical for fairly inexpensive 2 wheel vehicles.

2 stroke vs 4 stroke?
On a 2 stroke engine, each cylinder fires every time the piston comes up. On a 4 stroke engine, the cylinder only fires every OTHER time the piston comes up. 4 stroke engines have 4 strokes: Intake, compression, power, and exhaust. 2 stroke engines complete these cycles in only two strokes of the piston by use of ports in the cylinder walls. 2 stroke engines usually produce more power for a given weight/size. But, in gasoline engines, 2 stroke engines are typically less efficient (use more gas) and have much higher pollution levels (note: some newer "direct injection" 2 stroke engines do much better on pollution levels than the typical 2 stroke)
Are the tugboat engines are two stroke or four stroke?
For the most part, Tugboat Engines are LARGE two stroke (or two stroke cycle) Diesel Engines which provide High Combustion Temperatures and Pressures, High Horsepower typically > 1000 and High Torque, at relatively low speed. As an example of the two stroke diesel cycle engines ability to produce high horsepower and high torgue at low speed, The Union 6V Diesel was produced during World War Two as an engine for locomotives for the transport of industrial materials used in the production of weapons and armament. It was functionally an inline or straight block configuration, but because adjacent cylinders were actually offset from centerline by 6 degrees in opposite directions (cyl 1 offset to starboard by 6 deg from centerline and cyl 2 offset to port by 6 degrees from centerline, and so on) it was technically a V configuration. It was subsequently utilized by the Navy in a few instances as main propulsion for Yard Craft, mostly Yard Oilers (capable of hauling around 240K to 280K gallons of fuel to be loaded to ships at dock in a given harbor). This engine produces in excess of 1000 horsepower at a maximum 325 RPM. It idles at 125 RPM, and at that idle speed produces very large smoke rings out it's exhaust stack. This was also a naturally aspirated diesel (meaning it had no blower or turbocharger). It was also a directly reversible engine in that to reverse your direction of travel, the engine had to be shut down, the camshaft shifted utilizing a dual direction air cylinder, a pinion gear mechanically moved into position between the starter gear and the flywheel gear, and the engine then was restarted in the opposite rotation, turning the main output shaft in the opposite direction. No transmission or reduction gear.
How do you set timing on 2 stroke 2 cylinder engines?
Hi, The answer for your question would be, the timing will set based on crank angle position only as it is done in 4 stroke engine. It differs for a TBI based engine and GDI based engine.
What does number mean for Briggs engines?
Series # (e.g. 700, 825, 1150, etc.) is the gross torque rating (i.e. 1150 = 11.5 ft lbs.) (newer torque rated engines only) Model # (e.g. 095702) is the model designation signifying major mechanical features. In this case: 09 cubic inches, design type 5, crankshaft orientation 7 (vertical), bearing/mount type 0 (plain bearing, no flange mount), starter type 2 (Recoil (pull-type)). Type # (e.g. 0536-B1) identifies other mechanical features & specs, color, decals, top rpm, etc. Code # (e.g. 08102801) indicates date and location of manufacture (i.e. yy/mm/dd/location = Oct. 28th, 2008, at plant number one)
How locomotive compressor work?
3cd b is name of compressor , is using in diesel locomotive . Compressor has three stage of cylinders w pattern. There are 2 low pressure cylinder 1 is high pressure, low pressure has 2 inlet & 2 discharge valve . Atmosphere air comes from air intake filters through inlet valve open position into low pressure cylinders via inter cooler get cooled goes to high pressure cylinder . The cooling improves the volumetric efficiency of the compressor. The fan the finned tubes of the inter cooler increses the cooling efficiency. After well compressed air from high pressure goes to after cooler & way to mr tank for air brake system. So compressor only used for air brake locomotives.
Why diesel not used in two wheelers?
there are some 2 wheelers with diesel engine
Where 2 stroke diesel and petrol engine used?
two stroke diesel engine is used in cargo ships as cross head type engines, two stroke petrol engines used in two wheelers.
Why 2 stroke diesel engines are not used in two wheelers?
Two stroke engines will create a lot of visible smoke pollution and also more noise than four stroke engines. For these reason, many countries have required that all new motorcycles should be four-stroke.
What are differences from 2 wheelers and 4 wheelers?
2 wheelers have 2 wheels 4 wheelers have 4 wheels
How many strokes for diesel engine?
Diesel engines can be built in both 2-stroke and 4-stroke
What problems did the diesel engine have?
1. Diesel engines, because they have much higher compression ratios (20:1 for a typical diesel vs. 8:1 for a typical gasoline engine), must have thicker metal castings so tend to be heavier than an equivalent gasoline engine.2. Diesel engines also tend to be more expensive to buy. However, because diesels can do more miles per gallon, they are well worth the extra money because, but, if you do a big annual mileage, they will save you money buying diesel fuel instead of gasoline.3. Diesel engines, because of their weight and compression ratio, tend to have lower maximum RPM ranges than gasoline engines. This makes diesel engines high torque rather than high horsepower, and that tends to make diesel cars slower in terms of acceleration. The latest designs of diesel engine have performances which are almost as good as as gasoline engines.4. Diesel engines must be fuel injected, and in the past fuel injection was expensive and less reliable. Nowadays many gasoline engines also use fuel injection systems and the designs of both the injector fuel pumps - and the injectors themselves - have been improved to make them very reliable.5. Diesel engines tend to produce more smoke and "smell funny." Nowadays, provided they are serviced correctly, diesel engines don't emit more smoke.6. Diesel engines are harder to start in cold weather, and if they contain glow plugs, diesel engines can require you to wait before starting the engine so the glow plugs can heat up. Modern diesel engines don't have that problem.7. Diesel engines used to be much noisier and tended to vibrate. Modern diesel engines can be almost as quiet as gasoline engines and they don't vibrate so much.8. In some places diesel fuel is less readily available than gasoline.
How do engines run?
What kind of engine? There's steam, gasoline, diesel, 4 stroke, 2 stroke.
Why is there 2 batteries on a 2005 F250?
Diesel engines need more cranking power than what one battery provides.Diesel engines need more cranking power than what one battery provides.
What are the basic important components of IC engine?
The air intake system, carbourator or fuel injection system, combustion chamber, ignition source (spark or compression), and exhaust port or valve. This is very broad you could find much more by specifics looking into 4 stoke gasoline engines, 2 stroke gasoline engines, 4 stroke Diesel engines, and 2 stroke Diesel engines.
Why is a 2 stroke diesel engine used for marine propulsion engines rather than 4 stroke engines?
because iring nag gakos ( cats are embracing)
What will happen if diesel filled in petrol engine?
the engine will not run because of three reasons. 1. Diesel uses more compression than the petrol engine does 2. the diesel engines fuel to air mixture is 1:1 and petrol isn't 3. diesel engines use straight compression or glow plugs instead of spark plugs
Do Diesel engines use a lot of oil over a short period of time?
