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.

How does a Bollinger engine work?

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.

What are diesel engines?

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.
