MotoGP engine – MotoGP engine powers arrive at a level hardly to overcome. The new rules don’t allow to grow the horses limit. They force engineers to work up on a number of other aspects.
Since the MotoGP used the 1000cc engines again, in 2012, the greatest power grows slowed than the previous years. It’s just looking at data on the maximum speeds recorded in various circuits. In particular, we can watch the best lap average during the official qualifying round. For example, what happened to the Circuit de Catalunya, one of the most significant for maximum speed? During the 2013 qualifying the most fast on the straight line was Valentino Rossi with Ducati. The Italian champion recorded an average of 337.4 km/h. While, in 2016, Andrea Iannone recorded 341 km/h.
MotoGP engine, all constructors are “obligated” to draw 4 cylinders
How the development of the Ducati’s engine gained about 4 mph in three-four seasons? First. We talk about the MotoGP technical regulations. Since 2012, the bore of these motors must be a maximum of 81 mm. Even the fractionation must be not more than 4 cylinders. For this reason, all constructors are “obligated” to draw 4 cylinders. A 3-cylinder or a 2-cylinder would need a larger bore. If it wants to express a maximum power.
A modern naturally aspirated 4-stroke engine has its power directly linked to the extension of the pistons total surface. Because if you want to have more horses, it must be to get inside the combustion chambers more air/fuel mixture. The engine takes in air at atmospheric pressure. It’s the only way to get more air is enlarging the ducts and increases the surface area of the sky.
So, the engine has a better bore that spins at a higher regime. Since 2012, the teams can’t do this. To increase power, the designers must improve the engine air intake and exhaust capacity. They improve combustion, reduction of losses due to internal friction. However, these aspects are already extreme for the advanced engines. Then, the growth of performance is really very difficult.
MotoGP engine, Honda chooses to work his V4 at high RPM
Honda chooses to work his V4 engine at high RPM. Marquez and Pedrosa’s bikes, and other Honda, sound much more acute than all other MotoGP’s motorcycles. In the last two seasons, however, pilots talked about the difficulty to manage the power of the engine. In 2016, the move to unique software-created further difficulties to the extent. So, Honda gave up the performance.
Maybe Ducati has the most “full” engine. It associates highs explosive and powerful bass regime that everyone would like to have. Instead, the Yamaha M1’S maximum power is not at the top. But the Japanese brand has shown that this aspect is not crucial.
