I own all the books mentioned above.
Motorcycle Dynamics is the most technical. I haven't read it yet.
I also recommend.
The Racing Motorcycle: A Technical Guide for Constructors, Volume 1 by John Bradley. Volume 2 is more construction oriented but has some interesting stuff on materials...
Could someone explain to me the difference between radiator caps with a spring pressed normally closed vacuum valve and a weighted normally open vacuum valve in the context of a automotive cooling system. Thanks.
WilliamH, The solenoid characteristics you are talking about show up as increased current rise time right?
The problem I am trying to figure out is what happens when you increase the boost to 60psig, or more. I want to run the injector at a constant differential pressure but I fear that as I...
Are their any general rules of thumb for throttle area size vs. airflow (acfm) fon an engine. How does this change for a naturally aspirated vs. turbocharged?
Thanks.
Warpspeed, The way I understand it, by mass of fuel, as long as the delta P across the injector is the same the mass injected will be the same at a set dutycycle and temperature.
The problem I am trying to figure what happens at high fuel rail pressures. If an injector is designed for 70psi...
I have a question that is probably so stupid I am embarrassed asking it.
Say you have a turbocharged CNG engine. Say the fuel rail pressure is 70psi across the injector. Say the injector will not open past 100psi at atmospheric pressure. Will the injector open with 30 psi guage manifold...
Texaspete,
Thanks for the reply. The plotter is attached to the serial port.
Hp dosn't support this printer anymore so I didn't find any drivers on their site. In the windows add a printer wizzard they list the HP draftmaster rx so dosn't that mean windows already has a driver built in?
I...
I would like to plot with a HP Draftmaster RX HP-GL/2 Plotter.
So far I haven't had any luck. I am using windows xp and pro/E 2000.
Has anybody been able to get this combination to work?
How did you do it?
Thanks,
Jason
I have a few questions about turbo chargers at altitude.
First off has anyone dyno'd the same engine at standard conditions, then dyno'd the engine at altitude. How do the true hp readings compare?
Are their any hp correction factors for turbo engines? How good are they?
Finally happens when...
Hi,
Does anyone know of a test spec for manifold air temperature for running a heavy duty turbocharged intercooled engine on a engine dyno. Is their a CARB Spec.? What do the OEM's like CAT, Cumming, John Deere typically use?
Thanks
I would like to create a 3D surface plot from a data set of (x,y,z) data points. Help says, "you can create a surface plot from a set of x,y and z data points. Create a surface plot region and type the names of the x, y, and z vectors separated by commas into the placeholder." I think I tried...
I was wondering if any out there is familiar with the AVL 8 Mode Heavy-Duty Cycle engine test proceedure. I have a few questions. Why do the weight factors not add up to 100? Is it correct that you weight the [g/hr] emissions from the 8 modes and the [hp] from the 8 modes then divide those...
Here are a few links of pickup trucks converted to use hydrogen enhanced compressed natural gas (HCNG). The concept is simmilar to hythane, just higher precentages of Hydrogen. Using higher percentages of hydrogen has definite emmsisions advantages.
