What is the difference of marine diesel engine to an ordinary diesel engine?
Diesel engines are all fuel injected and are designed for ignition using compression. Automotive gasoline marine engines that use a carburetor have a strengthened body to prevent fires.
What are the marine diesel engine types?
Marine diesel engine types are the two-stroke cycle and the four-stroke cycle. Invented by Rudolph Diesel in 1892, a diesel engine operates by igniting fuel inside a cylinder containing a piston. The piston’s motion then converts thermal energy into work.
Is marine diesel cheaper than diesel?
While not as fuel efficient as their diesel counterparts, they are much cheaper to purchase and maintain. Serviceability is arguably better for gas motors as almost every marine mechanic has some gas experience while a good outboard or diesel tech is becoming harder and harder to find.
How combustion takes place in a marine diesel engine?
As the air is compressed, it rises in temperature. When the piston reaches 19° before tdc, the injection of fuel commences and continues until 73° after tdc. The heat in the compressed air ignites the fuel and combustion takes place. The gases expand forcing the piston down on the power stroke.
What kind of engine does a Pathfinder have?
The design of the Pathfinder marine diesel engine was a reproduction of their very successful VW Golf and Caddy autos and Rabbit pickup diesel engines. These dry-land versions were very reliable, often returning 45mpg, and clocking up well over 100,000 trouble-free miles.
Where was the VW Pathfinder pickup truck made?
The Volkswagen Rabbit pickup truck diesel engine was designed and produced in the VW factory in Germany and was the forerunner of the Pathfinder Marine engine. The Pathfinder was produced at the VW Factory and later for over 12 years at the VW Marine works in Germany.
What kind of engine does a fishing boat use?
The Pathfinder Marine Diesel engine was a 50hp 1.6 liter VW industrial diesel engine formerly used in the VW Rabbit truck, where it gave a reliable economic service. It became a very popular engine with the fishing boats of Canada; some of these boats are still reliably propelled by a Pathfinder.
When to change belt on Pathfinder marine engine?
On Pathfinder/VW websites, there are various belt-change intervals quoted from 2000-3000 running hours; I have also seen somewhere that VW recommend 1000 running hours between timing belt renewals. Depending on the engine usage this seems a reasonable period.
