As a well-known Sino-American joint venture in the power equipment industry, Cummins diesel generator sets are widely favored in the industrial sector for their easy maintenance, strong economic performance, and excellent load response characteristics. To help users better manage equipment… Read More

High temperature-related failures in diesel generator sets rank among the top three failures in power systems, directly affecting the lifespan of the equipment and power supply safety. This article systematically analyzes the causes of high temperature and control mechanisms based… Read More

1. Mechanical Power System Inspection (1) Verify Engine Speed Use a mechanical tachometer to measure the diesel engine’s flywheel speed and ensure it reaches the generator’s rated speed (typically 1500/1800 rpm). Focus on checking if the electronic governor’s actuator is… Read More

The oil capacity of a diesel generator engine should be determined based on the specific model, power rating, and the manufacturer’s design. Below are common reference ranges and important considerations.

When a diesel generator set operates under overload conditions, the following problems may arise. These impacts often have a cascading effect and require special attention:

Diesel generator voltage instability or low voltage is a common operational fault that directly affects the quality of power supply. As an electrical engineer with 15 years of experience in the industry, I have handled hundreds of similar cases. Below,… Read More

The lagging and leading power factor of a diesel generators are important indicators that describe its output electrical characteristics and are closely related to the phase relationship between current and voltage. The Essence of Power FactorPower Factor (PF) represents the… Read More

The cylinder head gasket, though inconspicuous, is a crucial sealing component that ensures the normal operation of a diesel engine. If it ruptures, the consequences range from decreased vehicle performance to total engine failure. I. Typical Symptoms of Cylinder Head… Read More
