Chongqing Sanchai Power Group is a modern private enterprise which integrating “research, development, production and marketing”
Sanchai is the first private enterprise geting the production license of import high-horsepower engines.
Sanchai is the first private enterprise casting large engine parts by using cylinder block with EPC.
Sanchai is the first private enterprise with the advanced technology of the integral crankshaft with counterweight.
Sanchai has three registered trademarks: Kangfa NewStar, Sanchai and CCEC.
The modern diesel engine starts with a block, containing all the parts for the basic internal combustion process. There is an open space in the block for each cylinder, where the combustion process takes place.
The first piece we need is the crankshaft. This is the piece that converts the linear motion created by combustion into rotational motion.
Next we need something to connect the crankshaft to the cylinder and carry the force of the combustion to it. These are the connecting rods.
Each connecting rod attaches to a piston at the top. The pistons create the bottom of the combustion chamber and move up and down in the cylinder during operation.
At the top of the block is the cylinder head. This closes the top of the combustion cylinder to contain the force of the combustion event. The head can be one unit covering all the cylinders or multiples with each covering a portion of the cylinders, depending on the design.
Now that the cylinder is closed off, the engine needs valves to allow the combustion gases to flow out and fresh air to flow in during the process. There are usually two valves for exhaust and two for intake air on each cylinder.
The component for getting fuel inside the cylinder is probably the most complex part of the combustion system. Fuel injectors spray fuel into the top of the cylinder in very precise patterns with highly controlled timing.
Most engines still rely on a mechanical system to open and close the valves, and some still use mechanical actuation (instead of electrical) for the fuel injection. The camshaft’s revolutions control the timing of each event through the geometry and placement of the lobes on the shaft.
Now that we have built the engine block, let’s take a closer look at how these parts work together to produce a combustion event.
