Hi, Could anybody let me know if water injection can help to reduce the intake air temperature significantly in NA engines? I heard that it is mostly used in Turbocharged engines. And if it is useful Practically, is there any way to make a DIY version on a low budget? Engine: 1.6L, 112 BhP...

Dear all, I'd appreciate your help if you can point me to the right direction on how to write programs on PDAs running PocketPC 2002 or 2003 operating system. I need to interface with serial or USB port as well in my programs. I've heared about .NET compact Framework and so, but don't kow how...

Just was curious, with a very thin atmosphere in Mars (or somewhere in the space with almost nothing like vaccum)how it is possible to take the heat from electronic parts of a device like Mars rover and damp it out? Imagine the worst case that there is no air to conduct the heat, and you know...

Dear all, I'm an electronic engineer but never done PROTEL seriously before!! I'd like to design a circuit that will sit on a board with an odd shape, having holes and curves everywhere. Can I import the board shape from Autocad and design my PCB there? I usually prefered to design the small...

Daer all, I'm looking for a scantool (PC based )suitable for both personal and (potential) professional applications. The prices on the internet are very different while they offer more or less the same abilities. Do you have any idea or tested any of the products on the market? I found one...

I opened an ECU -> all the board and its components were sank in a pinkish kind of gum. Is it usual? and if it is, how to remove that stuff from the board safely? (Nothing was clear with that gum, I could only see a pink plane in front of me). Any help would be appresiated. Cheers You can...

I bought a TV Tuner for my laptop and was working properly in my country in the middle east. When I moved to England it CAN detect channels but there is no sound. When I use "fine tune" and shift the frequency -0.25MHz, sound comes BUT the image goes away (with the same laptop). Is...

Hi dear engineer friends, I've got my BS in Electrical and Control Engineering (5 year course) from one of the best non-US (from Asia) accredited university in the world with an average of 76%. I used to work (part time and contract) in an Automotive supplying parts company for four years...

Hi freinds, Does any body know how can I find some information about fuel delivery per millisecond (or minute,...) of a simens fuel injector, used in Opel Vectra 2.2, 16V, sold in the UK? I need it to measure the exact fuel consumption of an engine(on a test cell) by measuring the pulse width to...

Hi, New engines usually use 6 or 7 different modes for fuel injection and spark ignition timing (Start, warm up, open loop, closed loop, hard acceleration, deceleration). There is one map in the ECU that contains the open loop data, this is the one that always all people talking about; a 3-D...

Hi, I have been looking several days on the net to find some datasheet or technical notes or whatever about 28F512 Flash roms. But it seems there is nothing on the net. If someone has any datasheet or something I would appretiate it too much. Thanks in advance for any help. Regards If you...

Hi, Is there anybody there knows how I can amplify a signal with a simple op-amp (CA3140 or 741) with a variable gain which is controlled by a digital signal? Nothing extreme, i.e. signal in the range of mV and gain in the range of couple of hundreds, so output in a range of couple of volts. It...

Hi, Currently I'm designing a test cell for an engine. one of the sensors that I need is In-Cylinder pressure sensor. I know they are either piezo or the optical ones. Is there anybody has some practical information on how to mount them on the cylinder head and the possible sources on the...
