Honda, a player with a big brain hole, not only plays a role in the fields of automobiles and motorcycles, but also can not underestimate the research on jet aircraft. Recently, the explosion of Honda's patent for an engine technology allowed G to take a hard look. In general, the working volume (ie, displacement) of each cylinder of a car engine is exactly the same, and the piston reciprocates regularly, which is arguably the most basic rule. However, Honda adopted a new patented technology to break this "iron law" and made the engine's displacement per cylinder no longer the same. What is the meaning of Honda's doing this? Before an in-depth analysis, G Brother briefly described Honda's variable cylinder management technology (VCM). VCM is mainly used in Honda's 3.5L V6 i-VTEC naturally aspirated engine. It can automatically select a 3-cylinder or 6-cylinder operating mode based on the actual road conditions, vehicle load, driving demand, etc., in terms of power and fuel economy. Sex in order to perfect balance. Constrained by taxation factors, Honda has developed a 3.0L V6 i-VTEC naturally aspirated engine for China, also equipped with VCM, which significantly reduces fuel consumption while ensuring power. Both the Accord and the Geshitu have the choice of this engine. . Of course, there are similar variable-cylinder technology, General Group, Volkswagen Group, etc., not too much black technology ~ Honda's new engine patent can be said to be a complex and advanced version of the variable cylinder management technology. G has no idea how to name it, but the principle is basically understood: The new patent keeps the cylinder bore of each cylinder of the engine consistent. The difference is that the working volume of each cylinder is different, and the displacement is different; the difference in stroke is achieved by crankshafts of different lengths on the crankshaft, longer crank arms mean longer strokes and larger displacements, such as The graph shows R2>R3>R1>R4. What are the benefits of doing so? Let us first give a general case where the displacement of a 2.0L inline four-cylinder engine is 500cc per cylinder (the so-called gold displacement). When a variable cylinder management technology is introduced, this engine under different operating conditions The displacement will be the following possible conditions: 500cc, 1000cc, 1500cc, and 2000cc, corresponding to the four cases in which three, two, one, and zero cylinders do not participate in external work. The Honda patent can be described using this example. For the same 2.0L in-line four-cylinder engine, the cylinders are divided into four displacements of 300cc, 425cc, 600cc, and 675cc (for example only). After adding variable cylinder management, the total will be generated. 15 kinds of engine displacement, Honda played this time is arranged in combination, ah, G brother to come up with the passing mathematics to calculate for you... Obviously, the permutations and combinations of games allow the engines to have more displacement. Honda said that this technology is more adjustable than conventional variable-cylinder engines in terms of power and fuel economy. In addition, this patent also explains how to adjust the weight of each area of ​​the crankshaft and control the vibration of different frequencies. The confidential part G can not obtain information... Honda’s patented technology application was formally announced in March 2014 and announced in January this year. It applies to its in-line and V-type engines. As for whether to put into production is currently inconclusive.
