AI Thread Summary
To calculate the wheel radius, key parameters include the motor power, gear ratio, and torque values. The discussion raises questions about the vehicle's hydraulic drive system, steering mechanism, and motor configuration for the four wheels. Clarification is sought on how the power at the hydraulic motor exceeds that of the electric motor. Additional information such as a sketch or hydraulic diagram is requested for better understanding. Accurate calculations depend on these details to determine the effective wheel radius.

Welcome to PF.

Is this a hydraulically driven vehicle ?
Does it have normal steering or is it a skid steer vehicle ?
How many motors are used to drive the 4 wheels ?
Are the wheel motor(s) in series, or in parallel ?
How can the kW at the H-motor, be greater than the e-motor ?

Please attach a sketch of the device, and/or a hydraulic diagram.
 
Here's a video by “driving 4 answers” who seems to me to be well versed on the details of Internal Combustion engines. The video does cover something that's a bit shrouded in 'conspiracy theory', and he touches on that, but of course for phys.org, I'm only interested in the actual science involved. He analyzes the claim of achieving 100 mpg with a 427 cubic inch V8 1970 Ford Galaxy in 1977. Only the fuel supply system was modified. I was surprised that he feels the claim could have been...
Thread 'Turbocharging carbureted petrol 2 stroke engines'
Hi everyone, online I ve seen some images about 2 stroke carbureted turbo (motorcycle derivation engine). Now.. In the past in this forum some members spoke about turbocharging 2 stroke but not in sufficient detail. The intake and the exhaust are open at the same time and there are no valves like a 4 stroke. But if you search online you can find carbureted 2stroke turbo sled or the Am6 turbo. The question is: Is really possible turbocharge a 2 stroke carburated(NOT EFI)petrol engine and...
