Diesel Generator Tech

Cold Weather Starting  ( Note:  A water jacket heater is recommended for stand-by   generator set   applications installed in a cold climate.) Preheater The glow plug system supplies heat to the cylinders so that compression temperatures are sufficient to ignite the fuel. To aid in starting the genset engine when the temperature is 50 °F(10.0°C) or below, an intake air preheater is available. Preheater equipment consists of a hand-priming pump to pump fuel into the intake manifold, and a switch to turn on the glow plug which is electrically heated by the battery. Fuel burns in the intake manifold and heats the intake air. Warning :  Do not use vapor in conjunction with the preheater. To do so could result in a fire. Steps to use the preheater for cold starting: 1. Set the throttle in idle position. Turn the glow plug toggle switch to the “NO” position. The red indicator light must be on. 2. After the red light has been on for 20 seconds, start...

This article will tell you what you should pay attention to when starting the Cummins engines . If you are interested, please take a few minutes to read it. Staring the Engines Please note that starting requires that clean air and fuel are supplied to the combustion chambers in the proper quantities at the correct time. Normal Starting Procedure Warning:   Before starting, be sure that everyone is clear of the engine and equipment. If the fuel system is equipped with an over speed stop, push the “Reset” button before attempting to start the engine. 1. On engines equipped with an air activated prelube device, open the air valve to activate the piston in the prelube device which will lubricate all moving parts in the engine. Note: On engines equipped with an oil pressure safety switch, hold the fuel by-pass switch in the “start” position until the engine oil pressure reaches 7 to 10 psi (48 to 69 kpa); then, move it to the “run” position. 2. Set the throttle for i...

About the operating instruction of Cummins engines, it is divided into several parts. Here, we mainly talk about what should pay attention to before starting the engines. Keep reading. 1. New and Rebuilt Engines Break-in NT series Cummins engines are run-in on dynamometers before being shipped from the factory and are ready to be put to work. But the operator has an opportunity to establish conditions for optimum service life during initial 100 hours of service by complying the following guide. 1) Operating as much as possible at three-quarter throttle of load range. 2) Avoiding operation for long periods at engine idle speeds, or at the maximum horsepower levels in excess of five minutes. 3) Developing the habit of watching the engine instructions closely during operation and letting up on the throttle if the oil temperature reaches 250 degree Celsius F (121 degree Celsius) or the coolant temperature exceeds 195 degree Celsius F (91 degree Celsius). 4) Operating wit...
