Hi,
I have a single cylinder air-cooled 4 stroke motorcycle engine. I need to model the ECT/CHT (Engine coolant temp sensor or Cylinder head sensor, acronym really doesn't matter since the temperature sensor is mounted in the cylinder block, machining a small area in fins).
I had a thought...
Tony,
Regarding the Knock input signal as matt said, the knock signal noise signal increases with the RPM, and the ECU algorithm filters this noise, and by having a adaptive gain vs RPM lookup table, we will be able to identify the knock and the correction will automatically take place.
Why...
Lets take the two situations,
Scenario 1: When you are approaching a stop with the car in neutral: The Engine speed drops from 2500rpm (for eg) to the idle rpm, during this phase the deceleration fuel shut off kicks in and cuts the fuel. And as mentioned in previous post, the fueling restarts...
The idea of the toothed wheel is good but the catch is that, in worst cases the reverse rotation of the wheel will be identified only after a minimum of one rev (to identify the missing pulse or varied pitch teeth). This means that the wheel would have moved in reverse by a 7ft (say 30" wheel...
Hi,
How can I detect the reverse rotation of the Car wheel? I know that vehicles have VRS (Variable reluctance sensor) or Hall sensor for wheel speed sensing. I think, the voltage from the sensor will be the same, for both directions(since the trigger wheel in shaft will cut the flux). Is there...
Hi All,
Am beginner to Ansys Workspace v10. Am planning to do a thermal analysis of a PCB board with IC mounted on the board. This calls for applying a plastic material to IC device and a copper to the PCB baord. I have designed the two components in DesignModeler, but then they both get merged...
Hey Transient1,
I visited the http://www1.ansys.com/customer/ but access is denied because It say the customer number is not active. Can you please get any other sites which provide the tutorial for Ansys 10
Thanks!

Hi,
I am planning to fix a MAP sensor in a carbureted bike. Is there any precaution I need to follow while fixing the MAP sensor? My objective is to measure the manifold vacuum that exists in the manifold.
The bike has a 150cc, single cylinder engine. I have given the bike picture...
Yeah right! I accept both of ur views. I was also thinking that if i could have a Barometric sensor and a MAP i will be able to find out the differential pressure across the throttle body (replacing the need for the TPS, from i will be able to get the information about the Altitude compensation...
Hey TS,
Thankx for sharing for ur experience.
What happens if the air filter is clogged? How will the Speed-density system work, if the MAP is going to show erroneous value?

Hey Guys,
i was just wondering about the basic Electronic Fuel Injection System for a Samll Single cylinder engine? If I use the MAP sensor for the load sensing and Crankshaft Signal for Speed sensing (Basically Speed density method), can i get away with TPS (& use a normal mech throttle body)...
Hey All,
I was trying out the AutoCAD LT 2004 after a long time. I was using AutoCAD 2000 and did lot of 3D modelling with materials & rendering effects. But those options(3D model creation toolbars & rendering) are not there in AutoCAD 2004 LT. Have they removed those options or Any other...
Hi All,
i heard that Throttle plates are used in Diesel Engines recently for controlling Air for meeting the emissions norms Euro 5 or so (in CRDI systems). But is it that the Efficiency of the Diesel Engine will drop bcos of the this of Throttle plate? If at all the throttle plate is used...
You can generate a script file in AutoCAD that will help in executing commands, that will help you to animate.
Alternatively, if your objective or case is clearly fixed, then you can capture the object as images at different time interval and then run these image file together, using software...
Thanks Jb, Pat & Greg.
Jb, Megasquirt offers a MAP sensor mounted on the PCB, and
this just measures the abosulte air pressure rather than the intake manifold vaccum. Are you talking about the version in which we need to mount the MAP sensor seperately?
I am planning to use only four sensors...
I am planning to fit a Electronic Fuel Injection for a Single cylinder four stroke Two wheeler engine. I am planning to remove the carburettor and design the throttle body with butterfly valve and fit a Injector near the inlet port. I think there is no necessity for me to design a throttle body...
Do you have any idea, how to use pointers in simulink functions?
We normally declare all the variables as global and use them in functions in Stateflow, but this consumes lots of memory. So how can we pass variables to functions?
Hi All,
I have designed a simple non-inverting amplifier using LM358 with gain of 1.76 (Rf = 0.76K & R1 = 1K). I have given a supply voltage of +5V to the opamp. My input voltage varies from 0 to 5V. My problem is that the output from the opamp gets saturated at 3.6V(which is limited by the...
Hi,
I am an automobile engg, going into electronics field. Can anyone tell me the IC number of Op Amp whose excitation voltage is 5V?
Does LM741 take 5V supply voltage?
Thanks
AutoGuy
