Diesel Generator Tech

This article will introduce Starlight Shangchai Series diesel generato r in details. But first we should learn Shancghai diesel engine SDEC company.  Background of SDEC Company SDEC company was established in April, 1947. Over nearly 60 years, SDEC company have always adhered to the enterprise purpose of "Create momentum for the social progress, provide good product to enrich the users", and it has made a unrelenting commitment to the R&D, production and manufacturing of professional diesel engine.Currently, SDEC company has become a national oversize high-tech enterprises integrated with development, design, manufacturing and marketing, with the business scope of diesel engines, fuel system, diesel gensets and investment in running business, etc. Products has owned a complete product range of five categories with over 300 models: G128/135 C (121), D (114), P11C and 10. Their power range covers 60-600 horsepower. In 1994, the company became the first one amon...

Oil viscosity is very important for a diesel engine or a diesel generator. But how to judge the oil viscosity is good or not? Read this article and you will learn a lot.  Cummins generator engine oil viscosity  Viscosity is a measure of the resistance to flow offered when one layer of oil molecules move relative to an adjacent layer. This resistance comes from the friction generated by the oil molecules as they move past each other. This shearing action occurs constantly in the oil films lubricating all moving parts of an engine. The viscosity characteristics of all fluids are affected by temperature. Multi-grade oil viscosity tend to be less sensitive to temperature changes because of the addition of viscosity improvers in their formulation. The viscosity of multi-grade oils is also a function of their rate of shear, or the relative speed of moving parts. The lower the relative speed, the greater the apparent viscosity of most multi-grade oils. Most of the we...

Knowing about engine oil function is very important and necessary to prolong your machine service life. This article mainly talks about Cummins diesel generator engine oil function. If you are using Cummins power equipment, this post will be helpful.   Lubrication The primary function of the engine oil is to lubricate moving parts. The oil forms a hydrodynamic film between metal surfaces, preventing metal-to-metal contact and reducing friction. When the oil film is not sufficient to prevent metal-to-metal contact, the following occurs: ● Heat is generated through friction ● Local welding occurs ● Metal transfer results in scuffing or seizing. Extreme Pressure Wear Control Modern lubricants contain Extreme Pressure (EP) anti-wear additives. These additives form a chemically bonded molecular film on the metal surfaces at high pressures to prevent direct contact and wear when the load on the parts is high enough to eliminate the hydrodynamic oil fil...

Shangchai diesel engine adjustment instructions will include the following items: checking and adjusting valve clearance, checking inter-cooler and its lines, fan bearing , turbocharger, vibration damper, changing coolant and cleaning system and repairing air filter element. 5.3.17 Checking and adjusting valve clearance When doing the first maintenance for a new or overhauled engine, conduct valve-clearance checking to timely regulate and correct the initial changes of the valve clearances. Later valve clearance checking and regulating should be done based on the maintenance plan if the engine operates normally. Valve clearance checking should be conducted after the engine has been stopped and the coolant temperature falls to below 60℃. (1) Remove the nut on the valve cover and scrap the cover and scrap the seals and gaskets (2) Rotate the engine and make the piston of No. 1 cylinder position at the top dead center on the compression stroke. Note: When the indicator 11 0n...
