When Downtime Is Not An Option.


Common Rail Injector Maintenance: The Best Way to Keep Your Volvo Penta in Its Prime

The safest way to ensure your Volvo Penta diesel engine performs its best is to keep its common rail injectors clean and make sure they are operating properly. If the fuel injectors are not subjected to regular cleaning and maintenance, your engine will not deliver optimal results and will use far more fuel than it should.

If not cleaned regularly, deposits build up on the injector tips. This usually happens once the engine is shut down and there is still some fuel left on the fuel injector tips. These deposits interfere and mix with the clean fuel and can significantly hinder your engine’s performance.

Different Types of Marine Diesel Engines

Most contemporary boats run on diesel engines. In fact, diesel engines have been the powerhouses of boats for over 100 years. The first one was installed in a Danish ship Selandia in 1912. If you are looking to buy a boat, or are thinking of rebuilding your boat, one of the most important things on board is the engine. There are several different types of marine diesel engines to choose from. All have some advantages and some drawbacks. Listed below is a brief description of all types.

Why do boats have a diesel generator?

A large majority of boats are powered by diesel engines. These powerful machines are typically strong enough to provide propulsion and electricity for the whole vessel. However, these machines are also quite loud and can consume a lot of fuel. While the boat is moving, the main engine runs and powers everything on it.

 However, when the boat stops somewhere, main engines are typically shut off in order to save fuel. There is a drawback there; all the electricity is now provided by your onboard batteries. As with all batteries, their charge is far from infinite. Once the batteries are depleted, you have to restart your engine just to charge them again. Or, rather, you would have to do that if your boat didn’t have a power generator.

Fuel Injection San Diego Experts Explain the Basics of CRDI

Common rail Direct Injection or CRDI is a system used to inject fuel into the cylinders of a diesel engine directly, via a single line known as the common rail. This line is connected to all the fuel injectors inside the engine.
Traditional fuel-injection systems used in diesel engines relied on building up pressure for every injection cycle. The new systems maintain a constant pressure level at all times so that it is available through the fuel line at all times. The engine regulates the pressure depending on the load and the speed of the engine.

An electronic unit or ECU adjusts the pressure using sophisticated sensors placed throughout the engine. This way, injection and compression are independent and fuel can be injected when needed. This helps reduce dangerous emissions and saves valuable fuel.
