Although it was their farewell year, they chose to completely change the structure of the power plant to defeat Mercedes
EHonda F1 Engine Development Director Yasuaki Asaki revealed that they have been able to implement the most extreme development. This is the year he left Red Bull and they were able to fight for the World Cup. The technician explained the details of the improved elements in 2021, which is a global redesign of the unit used in 2020. For now, it seems to be comparable to Mercedes.
He said: “When Honda announced that we would withdraw from the sport, everything changed. I went to meet the Starling President and told him that we hope to adopt a new structure in the power plant in our final year. He I am very happy to accept this request,” he said. Memories.
“With the green light, our engineers began to work hard to prepare for the new season. Considering the scope of changes to the structure of the power plant, this is not an easy task.” The following are the main novelty details.
“First, we changed the design of the camshaft to make it more compact, and lowered its position to make it closer to the ground. We must also change the angle of the valve. The main thing is to improve the combustion efficiency of the camshaft. For this, we must Change the angle of the valve and the camshaft must be changed.”
“We also modified the cylinder head to make it smaller and more compact, which makes the way air flows on the cylinder head better. We also lowered the center of gravity of the ICE (internal combustion engine or engine block).”
“The other thing we want to change is the pitch of the cylinders. By reducing the distance between one cylinder and the other, we make the engine shorter and smaller.”
“On the old engine installed on the top of the gearbox, we still have a margin of arc, where the left margin is slightly offset from the right margin. Therefore, what we have to do is reverse offset on the new engine, so this part The right is forward and the left is backward. I believe you will appreciate that this is a brand new engine, and we have been able to do this. In just six months, we have tested it without any problems “
“The other thing we need to improve is that the combustion efficiency has been improved. The output of the camshaft has also been improved. Due to the influence of physical rules, the energy that can be stored has changed. This means that the energy of this amount of exhaust gas has been reduced. “
“So we have many different development goals, and we think we have achieved them. I think we can achieve everything we have to do to compete with Mercedes. We have a lot of cooperation with Red Bull to ensure that “we can start from this new Get the most benefit in the compact engine. Until the summer of 2020, we have been working hard to make it the largest engine before,” Asaki concluded.
