spacesailor Posted March 24 Share Posted March 24 Mostly , all that energy has dispersed into , then out the rear end of a small victim . W hen a large truck failed to stop at the bottom of the hill on " old Windsor " road , it ran into & punctured a LPG truck . We didn't know or see the crushed " Holden sedan " under that truck , untill someone saw the ' shiny ' chrome bumper . spacesailor Link to comment Share on other sites More sharing options...

old man emu Posted March 27 Share Posted March 27 I have two questions about EVs: 1. People say that it is so quiet while driving in an EV. When I am driving along in my ICE, the only noise created by the vehicle is the noise of the tyres on the road. Even as I sit here at my desk, I can hear the tyre noise of vehicles passing by on the highway from close on a half kilometre away. Why wouldn't you hear the tyre noise while you are driving in an EV? 2. Power steering and air conditioning are standard features of modern cars. In my ICE, the pressure pumps which operate thee systems is driven via a belt system which connects the pumps to the crankshaft. How are these pumps operated in an EV?

octave Posted March 28 Share Posted March 28 At faster speeds tyre noise is indeed the major source of noise whatever the source of power. At lower speeds, EVs are quieter. In fact many in ,any areas sound generators (acoustic systems) are mandatory under a certain speed. https://en.wikipedia.org/wiki/Electric_vehicle_warning_sounds#:~:text=The vehicle must make a,a maximum of 75 dBA. There are many complaints that at least at low speeds EVs are in fact too quiet. Power steering. https://www.vehicleservicepros.com/service-repair/article/53084009/the-rise-of-electric-power-steering This is done electrically and indeed is increasingly being utilized in IC vehicles. With the widespread use of Electric Power Steering (EPS) systems in recent years, the automotive industry has undergone a substantial upheaval. These systems provide better fuel efficiency, improved driving, increased reliability, and have almost completely replaced the conventional hydraulic power steering systems on most vehicles. Air con in an EV is an electrically operated heat pump. the Tesla aircon uses between 1 and 3 Kw. Nothing beats being out on a hot day with the car parked in the sum and being able to turn on the cooling 30 minutes before having to get in the car. 1 Link to comment Share on other sites More sharing options...
facthunter Posted March 28 Share Posted March 28 Electric Power steering has been around in ICE cars for a while. It would significantly reduce the likelihood of an OIL fire Nev Link to comment Share on other sites More sharing options...
old man emu Posted March 28 Share Posted March 28 Not having the power steering pump and the A/C compressor driven by the crankshaft would really improve a vehicle's fuel economy. I know that when the weather doesn't require the use of the A/C in my car, the range I can get from a full tank increases significantly. Isn't that one of the reasons we all pulled of the original radiator fan and bolted on electric ones? Link to comment Share on other sites More sharing options...
