How about Weichai 480 gas engine

1. OK. Horsepower: Weichai's 480-horsepower engine has a strong power output capacity, which is suitable for heavy transportation tasks that require high torque and high power. It can easily drive large heavy-duty vehicles and provide excellent transportation capacity.

2. Hanwei H480 horsepower Weichai is not bad, the thermal efficiency is 50% This is the first release. In fact, improving thermal efficiency has always been a big problem. Thermal efficiency and emissions have always been contradictory. However, since 2018, it has been constantly experimenting, improving a small change every time, and finally making great progress.

3. Weichai 480. The Weichai 460 engine has small horsepower, and the Weichai 480 engine has high horsepower and high fuel. The Weichai 460 engine has a low speed and relatively good horsepower. The Weichai 480 engine has a high speed, high fuel cost, and relatively poor horsepower.

4. Weichai 480. When the speed of the Weichai 480 generator is kept low and the high-end position is used, the engine will generally be more fuel-efficient in this case. Compared with the Weichai 550, the Weichai 480 is more fuel-efficient.

5. Compared with other engines, the Weichai 480 horsepower engine can save more than 5L of fuel per 100 kilometers.In addition, the number of cylinders of the Weichai 480-horsepower engine is 4 and the cylinder diameter is 80mm, which is named according to the number of cylinders and cylinder diameter, which is also one of the reasons for its fuel saving. Therefore, the horsepower of Weichai 480 is more fuel-efficient.

Weichai natural gas engine can't be turned on at a speed of 1,200. What is the reason?

1. Serious engine carbon accumulation: Cars always have the problem of carbon accumulation, including cylinder carbonization, throttle carbonisation, spark plug carbonization, intake carbonization, etc. When the engine accumulates too much carbon, it will affect the ignition energy, intake efficiency and air-fuel ratio of the car, resulting in unstable power output of the car, idling and acceleration jitter.

2, excessive carbon accumulation in the engine: When there is too much carbon accumulation inside the engine, the gasoline sprayed by the fuel nozzle of the starting vehicle will be absorbed by a large amount of carbon accumulation, resulting in too thin mixed gas and difficult start-up. The vehicle is easy to start only when the carbon-absorbed gasoline is saturated. Solution: It is recommended to clean the engine carbon frequently.

3. The speed of the gas engine is related to the speed adjuster and air pressure. The reason for the vehicle shaking is a problem with the idling control. The idle control system of the electronically controlled engine is mainly composed of sensors, signal control switches, electronic controllers and idle control valves.

How many kilometers can the Weichai lng natural gas engine run

1. According to the query of Automobile Jianghu.com, the Weichai engine can run 1.8 million kilometers. It adopts the reinforced design of the fuselage and cylinder head, high wear-resistant coating piston ring and tile shaft. Weichai has a life of 1.8 million kilometers, and the engine maintenance week The oil change period reaches 120,000 kilometers, which is reliable and durable, so the Weichai engine can run 600,000 kilometers.

2. In fact, the current domestic engine is basically okay.In order to achieve hundreds of thousands of kilometers without overhaul (except for a certain brand), but buying a micro-car is generally just a transition. It is more than 30,000 kilometers a year, and if you drive a car for three or five years, it will only take more than 100,000 kilometers at most, and there will be no problem.

3. According to the piston movement mode, it can be divided into two types: resurrecting plug internal combustion engine and rotary piston engine. According to the cylinder arrangement, it is divided into in-line engine, V-type engine, W-type engine and horizontally opposed engine, etc. According to the number of cylinders, it can be divided into single-cylinder engines and multi-cylinder engines.

4. As long as it is used accurately and maintained accurately, it is no problem for a diesel engine to use 500,000 kilometers. Maintenance at ordinary times is very important for the car engine. If it is not maintained on time, the life of the car engine will be reduced.

What is the fault of Weichai natural gas engine fault code collection SPN 101?

1. The appearance of the code SPN101 represents an abnormality of the air flow sensor, which causes the fault light of the dashboard to be on. The fuel injector can be cleaned without disassembly. While cleaning, the combustion chamber and the carbon accumulation on the top of the piston can be cleaned up. It is recommended that the car be cleaned every 20,000 kilometers. It can effectively avoid excessive carbon accumulation.

2. The spn fault code means: the moisture content in the vehicle fuel filter exceeds the standard. The car instrument spn is the fault code of the vehicle, which means that the moisture content in the vehicle's fuel filter exceeds the standard. There are three types of fuel filters: diesel filters, gasoline filters and natural gas filters.

3. The fault code of Weichai natural gas truck SPN102 FMI20 usually indicates that the exhaust gas recycling (EGR) system has failed. Specifically, SPN102 indicates the engine pressure signal, and FMI20 indicates that the data is out of range, which may be caused by EGR pipeline blockage, EGR valve cannot be closed or opened, EGR sensor failure and other problems.

4. Generally speaking, computer failures include two categories: hardware damage and software program errors. The former is a hard failure, and the latter is a soft failure. Hard failure can be divided into three categories: device failure, mechanical failure and human failure.
