Most of the time a diesel has a hard time starting when its cool. When they have a hard time starting when hot, it is usually caused by the fuel running back into the tank. Check for a cracked fuel filter housing or a cracked low pressure fuel line. It is possible you have the wrong fuel filter. Install a top quality name brand filter like Wiks or Baldwin that has an anti bleed back valve in the filter.

The engine is a 2 stroke 'semi' diesel. Inlet and exhaust are as per 'normal' two stroke diesel but the injected fuel is not ignited by compression alone as in a normal diesel. Instead a 'hot bulb' on the cylinder head is heated with a blow-lamp before starting and heat from this, transferred to a tube in the combustion chamber which ignites the fuel to start the engine. Once running the engine itself maintains the temperature. Often called a Hot Bulb Engine.


The Diesel cycle engine was named after the German engineer who invented it, Rudolf Diesel. A Diesel engine uses two principles: air gets hot when you compress it, and fuel will ignite if it gets hot enough. The engine compresses air introduced into the cylinder to a very high pressure. When fuel is injected it immediately ignites.


it gets hot, and ignites the diesel fuel that is injected by the fuel injectors.


Drain it and dilute with gas while engine is hot so that you can burn it out. You will be hard pressed to crank it cold on diesel. If the engine is cole, spray carb cleaner in carb to warm it and burn it clean.


0.25-0.35mm IN 0.35-0.45mm EX --> ENGINE HOT


nox is formed from the hot combustion air coming out of the diesel engine


a petrol engine needs to mix its air and fuel before passing it into the combustion chamber before being ignited diesel has its air mixture heated as the piston compresses it in the combustion chamber then the atomized diesel fuel is injected into the hot air and is ignited.


usually to cause an engine to diesel when shut off, the spark plugs are dirty or burned out.also check the timing


It will dramaticly reduce the fuels flashpoint causing the engine designed for diesel fuel to run hot and cause detination


Loss of power, poor fuel mileage, hard starting, and the converter will get red hot. Normally the check engine light will also come on.


Yes it can if the fuel gets hot enough to ignite as in leaking on a header.


hi have you sorted the problem out yet....its driving me nuts !!! Thanks


Diesel burns when in an open container, it is not as volatile as gasoline. If you flick a match into diesel fuel, it will typically go out unless it is hot enough to vaporize due to the temperature. In a diesel engine, the fuel explodes when it gets to the right temperature, caused by pressure.


In 1892 the German engineer Rudolf Diesel got a patent for his invention of the technology for a compression ignition engine.From that time onwards it was called a "Diesel Engine".Another opinionActually the date was 1891 that Diesel invented his engine, which became the "diesel" engine as we know it.However an earlier heavy fuel oil engine, called the "hot bulb" or "heavy oil" engine, was invented by Herbert Akroyd Stuart. It was working in 1886, much earlier than the Diesel's engine, but, unlike the "diesel", it had a low compression-ratio so that the fuel could not self-ignite, so it and was not actually a "compression ignition" engine.Wrongly Rudolf Diesel was accredited with being the designer of the heavy oil fuel engine which was named after him although documented history will show that Stuart, was the true inventor of the heavy oil fuel engine.CommentThis question is asking specifically about the inventor of the diesel engine, which is a compression-ignition engine. It is not asking about heavy fuel engines in general.For more information about Rudolf Diesel and Herbert Akroyd Stuart go to the Related Links shown below.


After extensive diagnosis of fuel and ignition system, I solved my 1996 Tacoma hot start problem by having the valve clearances set properly. Tight valves cause compression loss and hard starting when the engine is hot.


A hot engine may misfire due to the way the heat affects metals and how they make contact. The problem in a 2005 X type 2.0 diesel engine could be due to improper gapping on the spark plugs. Set them according to the car manufacturer's specifications to correct the problem.


That's all down to how hard you run the engine. They can get glowing hot up by the exhaust ports.


Hot chocolate. Hard lemonade. Hawaiian Punch.


Diesel engines uses the heat of compression in order to ignite the fuel that has been injected into the fuel chamber. Rather than using a spark plug like a benzine combustion engine, the diesel engine uses highly compressed hot air in order to achieve ignition.


Temperature inside the diesel engine combustion chamber is approximately 320 degree Centigrade Celsius.


Yes, the coolant is hot and under pressure so that makes the hoses hard.


No - they are not designed to run on gasoline. You need diesel fuel or some can be run on vegetable oil or cooking oil but not gas it will wreck your engine. It detinates too hot.


The turbocharger turbine housing and exhaust manifold on any state of the art high horsepower (per litre of displacement) diesel engine will glow red as it approaches full load condition.


Diesel is a type of internal combustion engine wherein the fuel is ignited solely by heat produced by rapid compression of the air in the cylinder. Not by an electrical spark as in a gasoline engine. As the cyl air is compressed the air becomes heated. Fuel is injected into the hot cylinder and is ignited by the heat alone
