How to choose the fuel for diesel generator sets? Most users may only know that they need to use diesel, but do you know what kind of diesel to use? The main fuel for diesel engines is diesel. Diesel is made from petroleum after refining and processing. Its main characteristics are low autoignition point, high density, strong stability, safe use, and low cost, but its volatility is poor. When the ambient temperature is low, the diesel engine is difficult to start. Light diesel is used for high-speed diesel engines, and heavy diesel is used for medium and low-speed diesel engines. The properties of diesel have a great influence on the power, economy and reliability of diesel engines.   The following are suggestions for selection   The performance, specifications and selection of diesel The lowest temperature at which diesel spontaneously ignites without external ignition is called the autoignition temperature of diesel. The autoignition performance of diesel is expressed by th...

How To Choose a Suitable and Reliable Generator Manufacturer from China?   When searching for a dependable generator manufacturer in China, it’s crucial to take into account several important factors. Here's a guide to help you make an informed decision:   1. Avoid Chasing Extremely Low Prices While it may be tempting to select the lowest-priced option, extremely low prices often come at the expense of product quality. As a professional manufacturer, we understand the real cost of producing a diesel generator. In the market, most manufacturers have similar engine costs, but how can some suppliers offer 15%-20% lower prices? The answer often lies in cutting corners: using thinner steel (1.5mm), low-quality paint, aluminum alternators, or even fake engines. When evaluating a quotation, always consider these factors to avoid sacrificing quality for cost.   2. Ensure the Diesel Engine Power Matches the Actual Power Requirements Some suppliers may reduce prices by using...

Factors Affecting Diesel Generator Fuel Consumption and Methods for Reducing Usage   When managing diesel generators, understanding the factors influence that diesel generator fuel consumption can significantly impact operational costs and efficiency. Factors such as load, engine condition, and environmental conditions play essential roles in the amount of fuel a diesel generator consumes. This article outlines these factors in detail and provides actionable solutions for reducing fuel consumption in diesel generators. 1. Load-Related Factors   Load Size: Diesel generators operate most efficiently when they are near full load, as the engine’s design works best close to its rated capacity. At lower loads, the generator uses more fuel to maintain auxiliary systems, even though the generated electrical output is less. For instance, a 1000 kW generator operates more efficiently at a 1000 kW load than at a 200 kW load, as low-load operations lead to higher fuel consumption d...
