Diesel Regulatory Scheme

These factors, in turn, depend on the optimal timing and load of diesel, a uniform distribution of the cylinders, fuel system work perfectly, the normal course of thermal process. Regulate marine diesel usually after installation on the ship, repair, bulkheads separate details of the mechanism of gas distribution, gas pumps, piston, changes in operating conditions swimming, as well as defects in the work. Regulation can be divided into the following stages: pre-regulation for non-working machine on the factory data and instructions, management of the so-called the indicator process (indicator diagram, the values of temperature and pressure of gas, air, cooling water, lube oil, etc.), mode selection and power control. In the first (preliminary) stage regulation include: checking and setting the geometric and timing necessary values the compression chamber in the engine cylinders, control of fuel injectors and fuel pumps. Pre-regulation should preceded by a detailed study of the passport marine diesel engine and its performance. In addition, you must carefully read the design of the engine and take them into account regulation. Installation and management of geometric phase distribution in the following order: check correctness of pointer dead pixels, set the required clearance between the rollers service valves and washers fist; verify the correctness of camshaft position is determined by the pre-compiled pattern valve timing.

Simultaneously check the state of boxing washers rollers, adjusting screws, etc. The normal value of the compression chamber is determined by its size and height. Chamber volume is most often found by filling it with oil, and height, ie, a value showing the distance from the top of the piston at his position at top dead center (ie VM) to the cylinder cover – is measured by lead-print.
