Engine troubleshooting

Excessive fuel consumption Engine fuel consumption fault: Excessive engine fuel consumption refers to its fuel consumption exceeding the specified standard value per 100 kilometers. Excessive fuel consumption results in poor engine economy. There are many factors that affect engine fuel consumption, including factors related to engine technology and chassis technology. 1. Fault phenomenon: The engine consumes too much fuel. 2. Common causes of malfunctions

Engine technical characteristics

1. The engine valve drive mechanism adopts a hydraulic supported ball rocker arm structure. Compared with the hydraulic tappet type valve drive mechanism commonly used in gasoline engines nowadays, this novel valve drive mechanism has the advantage of relatively small friction torque, so the required driving force is also small, which can effectively reduce engine power consumption and fuel consumption. 2. To effectively reduce the weight of the entire vehicle, the 1.4-liter gasoline engine adopts an aluminum alloy cylinder body, achieving a very obvious lightweight effect.

Layout of internal combustion engines

The engine can be said to be the most important part of a car, and its layout has a significant impact on the performance of the car. For sedans, the layout of the engine can be simply divided into three types: front, center, and rear. At present, most car models on the market use front engine, while center and rear engines are only used in a few performance sports cars.

Basic structure of internal combustion engines

Overview The engine body is the framework that constitutes the engine, serving as the foundation for the installation of various mechanisms and systems. It is equipped with all the main components and accessories of the engine, both inside and outside, and bears various loads. Therefore, the body must have sufficient strength and stiffness. The body assembly is mainly composed of parts such as cylinder block, cylinder sleeve, cylinder head, and cylinder gasket.

Basic parameters of internal combustion engines

displacement First, let's take a look at the most common engine parameter - engine displacement. The engine displacement is the total working volume of each cylinder in the engine, usually expressed in liters (L). The working volume of a cylinder refers to the volume of gas swept by the piston from top dead center to bottom dead center, also known as the single cylinder displacement, which depends on the cylinder diameter and piston stroke. Engine displacement is a very important engine parameter, which better represents the size of the engine than cylinder diameter and number. Many indicators of the engine are closely related to the displacement. Generally speaking, the larger the displacement, the greater the engine output power.

Classification of engines

External combustion engine External combustion engine, which means its fuel burns outside the engine, was invented by R. Stirling of Scotland in 1816, and is also known as Stirling engine. The engine converts the heat generated by combustion into kinetic energy, and Watt's improved steam engine is a typical external combustion engine. When a large amount of coal burns to generate heat and heat water into a large amount of steam, high pressure is generated, which in turn drives the machinery to do work, thus completing the transformation from thermal energy to kinetic energy. internal-combustion engine
