The unveiling of a Marine engine differs from that of a car engine.
Mar 10, 2018

The common differences are as follows:

1. Speed: medium and low speed machine is used in general ship machine, while the machine is used for high-speed machine. The medium and low speed machine is easy to drive the propeller, and because of the low speed, the wear is smaller.

2. Test: ship machine test run propulsive characteristics (propulsive characteristics of diesel engine, diesel engine according to the characteristics of propeller work, each performance index and parameters with engine speed or load change rule), and there is no car machine.

3. The application of new technology: when the car machine, use ems ship machine is mostly used mechanical pump (of course, it's also useful to the high pressure common rail, but very few, many machines used abroad, but domestic appeared to have a the Chinese heavy industry, diesel engine factory of 6 cs21/32 (I don't know if I didn't remember) is made of high pressure common rail, recently like yuchai and nanyue electronic developing electric monomer pump vessel machine also trial), because the ship machine update more slowly.

4. Emission regulations: the vehicle is in compliance with 3, 4, 5, 3, 4, 5, and the ship is in compliance with Tier1, 2 and 3.

Small vessels with the engine of the knights and truck is similar, the characteristics of large Marine engine besides big is slow speed, can be slow to no retarding mechanism, direct drive screw, so it can burn heavy fuel oil, one may ask no retarding mechanism of propeller how to reverse back, well, as long as you can imagine this engine can solve the reversal that is very good.
