A CAT320 hydraulic excavator appears the following symptoms after 5100H of work: When the machine walks 30m forward, the whole machine has left deviation 2m; After 30m backward, the machine also moves 2m to the left.

QSB3.3 inherits the mechanical characteristics of the B3.3 engine and becomes the first small construction machinery diesel engine that perfectly combines full electronic control with high pressure common rail fuel system ( HPCR ) in the same size engine.

The Cummins QSX15-G7 is a high-performance diesel engine that meets the National IV emission standards. It adopts advanced high-pressure common rail fuel injection technology, electronic control system, and turbocharging technology, which is efficient, energy-saving, environmentally friendly, and reliable.

The 1106D-70TA carried by the XG822 22T excavator of Xiagong ™， Powerful and equipped with mechanical fuel injection, the maximum power can reach 129kW. This model of engine is fully designed and manufactured by SWAFLY Wuxi Engine Industrial Park. The primary consideration for the design engineer team is how to thoroughly solve the problem of different fuel qualities affecting engine performance. As a result, by adopting a fully upgraded fuel system, the engine's adaptability to poor fuel products was significantly improved. With the assistance of improved filters, any possible debris in the fuel was effectively collected.

Cummins engines, known for their efficiency, reliability, and powerful output, are widely used in various fields such as automobiles, ships, and construction machinery. However, overheating is a potential issue that cannot be overlooked for any type of engine. So, are Cummins engines prone to overheating? This question requires a deep dive from multiple perspectives.

I often hear some experienced workers saying, “Your excavator engine is direct injection, while your excavator engine is electronically injected.” Those who have been in the industry for many years know the distinctions between direct injection and electronic injection. But for those of us who are new to the field, how do we distinguish between direct and electronic injection? Today, I will share the differences between them.
