A car engine is like a human heart. The engine is heart and source of vehicle's energy. The quality of engine directly determines power of car.
As Japanese engine that was searched for all time, it is still controversial. Please note that ratings are indiscriminate!
The thermal efficiency of new Camry 2.0 engine is 41%
Subaru's horizontally opposed engine keeps center of gravity as low as possible. Subaru is a sub-brand of Toyota.
Toyota is conservative. Compared to Honda's aggressiveness, Toyota likes to do research and development on thermal efficiency and fuel economy, and Toyota engines have always been stable, with extremely low failure rates. The Toyota engine also has its own housekeeping skills, namely hybrid power system. Since future main power of 2.5L inline four-cylinder engine with "Dynamic Force Engin" direct injection, maximum thermal efficiency of HEV version has reached an astonishing 41%. It's also unmatched. Speaking of Toyota, it should be compared with Honda, in general, as soon as Honda has a new technology, it will immediately get into car, and car owner will be the first batch of guinea pigs. As for Toyota, like Toyota's new "Fengchao" platform recently, Toyota had already developed it in-house, and it was only tested for a few years before it was finally launched.
Honda engines go further and further down path of "black technology", almost "crazy". As world's largest engine manufacturer, Honda owns three major black technologies VTEC, i-VTEC and Earth Dream, and continues to lead way in technology. While ensuring stability of car, maximum power and fuel consumption of car. Honda uses black technology not only in car engines, but also in motorcycle engines. Thus, buying a Honda means "buying an engine and giving away car." So far, many people have become "faith fans" of Honda, and "Earth Dream" has become a "nightmare". It's possible that Honda's over-aggressiveness caused CRV engine throttle incident to flare up. In addition, since Honda uses direct injection into cylinder, a lot of carbon remains and additives must be added for subsequent maintenance, which increases maintenance costs.
As one of three Japanese giants, Nissan engine is clearly much weaker than Nissan "Ryota", with average reliability and manufacturability. least, on "big sofa" Nissan sit comfortably. Nissan VQ series engines have good dynamic performance and perfect NVH performance, and have won many reputations.
However, we often come across Nissan HR series engines that are not hidden in general.
Mazda is known for its Chuangchi blue sky engine technology. Of course, old Maliu didn't have that name before. From rotary engine to Chuangchi blue sky engine, Mazda is a true tech nerd. Mazda's engine is chasing a high compression ratio, and ultra-high compression ratio of Mazda's "two field" engine is also incomparable. It cannot be denied that Chuangchi Blue Sky engine still has many bright spots as a self-priming engine. However, Mazda has good power, good fuel economy ratio and good control. This is not only merit of engine. It is equipped with Sky Sky chassis and Sky Sky gearbox, which can block car's output torque when cornering, improve handling and stability, and also achieve good fuel consumption.
Mitsubishi can be considered worst Japanese hybrid so far, but Mitsubishi engine is mentor of domestic cars. At first, all domestic cars started with Mitsubishi engines, and then their own brands continued to grow. Mitsubishi engines support half sky of domestically produced vehicles. Mitsubishi has no Mitsubishi other than EVO. The engines used in initial cars of many factory brands are from Mitsubishi, for example old H6 uses Mitsubishi 4G69 series engines. The 4G engine series is regarded as Mitsubishi's best-selling engine series. With advent of own brands, Mitsubishi engines are lagging behind, even yielding to domestic engines. Mitsubishi is now showing less and less in front of everyone. However, Mitsubishi engine is still engine many emerging domestic car brands love to use, and it continues to make a fortune in silence.
Suzuki's performance in China is poor, not as good as Mitsubishi's, Alto is a thing of past. But Suzuki engine is still very good. Even though it is very small, engine still has a large bright spot. The Suzuki engine is probably more durable than Toyota, very durable. Since engine development plan with Volkswagen failed, I invested in research and development of a new generation of subcompact turbocharged engine, 1.4-liter BOOSTERJET engine. And rushed to Vitra. Vitara, a small off-road vehicle, can be considered "outstanding" generation in off-road world. So don't underestimate Suzuki.
Just listed a few Japanese engines, each has its own advantages, none is strongest, and there is no particular disadvantage, as long as you like it. The editor has a few words about car engine, most engine breakdowns occur due to fault of car owner himself, use of low-quality gasoline and engine oil, untimely maintenance, replacement of inappropriate engine oil at will, not cleaning carbon deposits, not changing spark plugs, etc. when car service master offered to replace them, he felt that he was being deceived. If there is a problem and it is too expensive, I will replace it with a poor quality product.
