Analysis of specifications and customs transaction analysischaracteristics of Honda 90 engine Honda 90 engine is a classic automobile engine, which is widely used in many Honda cars, such as Civic, Accord, etc. The following will analyze the specifications and characteristics of the Honda 90 engine in detail. I. Specification analysis 1. Displacement The displacement of the Honda 90 engine is 1.8 liters. This displacement belongs to a small-distction car engine, compared with itsIts large-dispement engine is more economical, energy-saving and environmentally friendly, suitable for urban walking and long-distance travel. Two. Cylinder diameter and stroke The cylinder diameter and stroke of the Honda 90 engine are 81 x 87.3 mm respectively. This parameter is an important factor in determining the size of the displacement, and it is also the basis for the engine output power and torque. For small displacement engines, such a cylinder diameter stroke size is relatively reasonable, has good balance, and stability can Damn it. 3. The maximum output power of the Honda 90 engine is 104 kilowatts, which is equivalent to 141 horsepower. This figure can be said to be a fairly high level for a 1.8-liter displacement engine, with strong power output capacity. Four. The maximum torque of the Honda 90 engine is 174 Nm, compared with the engine of the same level., the torque performance is good, which can ensure that the vehicle provides abundant power when accelerating, and can also have stable performance when driving at high speed. 5. Valve control system The Honda 90 engine adopts i-VTEC intelligent valve control system, which can automatically adjust the opening volume and closing time of the valve during inlet and exhaust according to the speed and load of the locomotive, so as to optimize the combustion effect and improve the power and economy of the engine. 6. The gearbox Honda 90 engine is usually equipped with a five-speed manual or five-speed automatic transmission. The manual transmission has the advantages of fast gear shifting and good driving experience, while the automatic transmission is easy to operate and more comfortable. II. Characteristic Analysis 1. Good fuel economy. Due to the small displacement design of the Honda 90 engine, coupled with the adoption of i-VTEC intelligent valve control system, the carThe car can accurately control the injection of fuel during operation, which improves the efficiency of fuel utilization, and greatly improves reliability and economy. Two. The Honda 90 engine with good noise control also performs well in noise control. The cast iron oil safer and cylinder liner are used to effectively avoid noise and resonance. In addition, the structure of its cylinder head has also been optimized, which can effectively prevent the spread of noise and vibration in the machine. 3. Outstanding power performance Although the Honda 90 engine is a small-displacement engine, its power performance is very outstanding. The intelligent valve control system maximizes the power output efficiency of the car, so that it can produce relatively good power output in acceleration, start and high-speed driving. Four. The Honda 90 engine with high reliability has always been Honda's most reliable engine in terms of quality. Adopted in various partsIt is a high-quality raw material and advanced production technology, which perfectly combines stability, durability and reliability, leaving a deep impression on people. Summary: Although the Honda 90 engine has a relatively small displacement, it has become a popular car engine with excellent fuel economy, stable and reliable performance and precise automated valve control system, bringing an excellent driving experience to the majority of consumers.
