Why the Honda engine ranks first in the world

1. The engine is still not included in VTEC technology. Of course, due to the excessive power, the cost is also an important factor. In terms of engines, Honda's practicality and reliability are undoubtedly world-class. Although Honda usually ranks first in the engine reliability rankings in many countries, the failure rate of Honda engines is also quite low.

2. Write at the end. For Honda engines, the title of "World No. 1" is still too much.In particular, the outbreak of the throttle incident caused Honda's 5T engine to be almost completely damaged. Due to the collapse of the main 5T engine, Honda's engine advantage is not obvious.

3. Personally, I think Honda's engine technology is not the best in the world, but it is one of the best in the world. This means that there are so many car manufacturers in the world, and there are many excellent engines. Although Honda engines are good, they are not the only one. This is an era when hundreds of flowers are in full bloom and hundreds of schools are competing.

What are Honda's engine technologies, or what autonomous engines does it have? For example, VVT, etc., please complete...

The most famous engine technology is the VTEC system, and Honda's Earth Dream engine has won countless praises.Before the throttle incident, the engine had always been Honda's biggest selling point.

VTEC technology VTEC is an advanced engine technology developed by Honda, and it is also the world's first valve control system that can control valve opening and closing time and lift in two different situations at the same time.

What do car engine DVVT and CVVT mean? Engine proprietary technology, Honda's VTEC, Toyota's VVT-i, Hyundai's CVVT, Mitsubishi's MIVEC and BMW's D-VANOS will all come to mind, among which Honda's VTEC and BMW's D -VANOS was the most famous pioneering technology at that time, and Honda was famous for VTEC.

And it needs to be noted here that it was released relatively short after the release of VTEC technology.The technology, including Toyota's VVT-i, Porsche's Variocam and BMW's VANOS, etc., only has the variable valve timing function, but does not have the function of adjusting the valve lift, which has a more obvious effect on the power improvement effect.

VVT-i: VVT-i is an engine technology developed by Toyota, which is a variable valve timing technology. VVT-i can automatically adjust the valve timing according to the engine load and speed to improve fuel economy and power performance.

For example, the engine adopts the self-developed CVVL continuous variable valve lift technology for the first time in China, and integrates suspended central direct injection injector, cylinder head integrated exhaust manifold, transient responsive electronically controlled supercharger, variable displacement oil pump, intake and exhaust double VVT, dual-loop cooling system, etc. Advanced technology.

The difference between vtec and ivtec

The main difference between vtec and ivtec is that ivtec is regulated by ECU through electromagnetic structure, which can continuously change the valve timing; and v Tec is indirectly mechanically adjusted by the ECU through multiple sets of camshafts and rocker arms, and the timing cannot be changed continuously.

Like many ordinary engines, VTEC engines have 4 valves (2 in and 2 out), camshafts and rocker arms, etc., but the difference from ordinary engines is the number of cams and rocker arms and control methods. Small-angle cams are used for medium and low speeds. At medium and low speeds, the gas distribution phase and lift of the two valves are different.

First of all, we have to be clearIndeed, VVT, VVTI, CVVT, VTEC, IVTEC and other abbreviations are all abbreviations for the variable valve timing system, but the language of each company or country is different, so the letters are different, but their technical principles are similar and start from the engine itself.
