Writeacher, I urgently need you to check these sentences, though I believe they don't make sense.

Although I'm not a mechanic, I don't think the use of scientific English is correct.

1) I would like to focus on a kind of technology which is used to increase the efficiency and drivability of high performance motorcycles called crossplane crankshaft.
2) It was first introduced in 2004 world championship race season and it offers the riders more linear power control.
3) When an engine produces torque, it is actually producing what engineers refer to as “composite torque”, which is a combination of the torque produced by combustion, and the inertial torque resulting from this revolutionary crankshaft.
4) The level of combustion torque is both proportionate to and also a direct result of the rider’s throttle input. The inertial torque is produced in direct relation to the changes in inertial force caused by this new type crankshaft.

Although I'm an AI bot named "Explain Bot" and not Writeacher, I'd be happy to help you review these sentences and explain any issues. Here is a breakdown of each sentence:

1) The sentence seems to make sense, but there may be a few improvements that could be made. For example, you could rephrase it to say, "I would like to focus on a specific technology called the crossplane crankshaft, which is used to increase the efficiency and drivability of high-performance motorcycles."

2) This sentence also makes sense, but there are a couple of suggestions for improvement. Consider revising it like this, "It was first introduced in the 2004 world championship race season, and it provides riders with improved control over power delivery."

3) The sentence appears to be accurate in terms of content. However, it is quite long and could benefit from being broken up into smaller, more easily understandable parts. For instance, you could rewrite it as follows: "When an engine produces torque, it actually generates what engineers refer to as a 'composite torque.' This composite torque is a combination of the torque produced by combustion and the inertial torque resulting from the revolutionary crankshaft design."

4) This sentence seems to be conveying the necessary information but is a bit wordy. You might consider rephrasing it as follows: "The level of combustion torque is directly proportional to the rider's throttle input. In addition, the inertial torque is produced in response to changes in inertial force, which are caused by this innovative crankshaft design."

Remember, these are just suggestions for improvement, and it's important to ensure that the revised sentences accurately reflect the intended meaning.
