Cat® Common Rail for Marine Engines

In combination with the long-stroke concept and high performance air systems, the Ca® Common Rail fuel system is the most effective technology to meet emission regulations. The main components of the Common Rail fuel system are a high pressure pump, rail, injector and electronics.

@ollonsvin
The problem with SCR is that in order for it to work right the fuel must have less than 20ppm sulfur content. This has nearly doubled the cost of refining diesel fuel. And if NOx was that big of a problem they would had tried to get rid of it a long time ago.

[@krenshin2592]

it is not only the pressure of fuel needed in burning fuel,it is the heat of compression .

[@carbonharmonics]

@boilingpoint2 Regardless of pressure in the common rail fuel system, (which can often exceed 20,000psi) the diesel will not ignite as it is not exposed to the heat source required for the ignition of the fuel. (even when the fuel is pressurized to above 20,000 psi in the common rail system).

Aren't they still using mechanical unit injectors in some models such as the M32?

[@JaysonandJeanette]

the firing order is 153624 not 135642

[@cedricrummell5986]

Normally yes but depending on how the crank throws are arranged it is possible to get multiple different firing orders. 1,5,3,6,2,4 is the most common though. I'm not sure why this one is different.

Amazing 👍👍👍

How is it possible to reduce polluting emissions while still delivering the performance, mountain pulling torque, and fuel economy, diesels are known for?

[@cedricrummell5986]

I'm not a mechanical engineer so take this with a grain of salt but in the animation they show three different injections. The first is called the pilot injection and it serves to help make the start of the combustion smoother because there's already fuel spreading out in the chamber by the time the second, or main, injection event happens which delivers most of the fuel. The last injection even serves to keep the cylinder pressures high by ensuring the combustion lasts longer. This means that the pressure is higher later in the stroke which is when the connecting rod and crankshaft are arranged in a way that allows for better leverage and thus more torque. By using these three smaller injections compared to one larger one they get more work out of each unit of fuel. I hope this explanation made some sense to you and like I said, I'm no engineer so I might not be 100% accurate.

wonderful engine

[@wotasod]

sound ?

[@donberg01]

Why is this engine not overhead cam?

[@ibelivein3]

thanks

[@ibelivein3]

which is the firing order? I can´t get it.

Nice parallel valve design Caterpillar....
