Hi i Have a question about bmw's engine. Everyone knows thats engine this company have a rod bearings problem. But nobody excatly know why is that? In Web we can search lot of reason. 1. Bad oil and too rarely change. BMW recommend 10W60 and perhaps it is a thick oil and when it's cold start the...

Basically it's a well known reaction, many kids on youtube make it for the views: I am thinking, since AlI3 sublimes can it be put in say tungsten bottle (is this even a thing??) and then used as a rocket the same way Na+H2O or HCL+Al rockets are used - the gas escapes? This phase...

Hello all, This is my first post on here so sorry if its not the greatest. I am starting to make a car based video game for the ios in which you are able to customise cars and race them. One feature i wanted to include in this game was the ability to create unique engines. I don't want it...

I found this interesting engine design on the internet. It is one of the most powerful and largest machines human have ever designed. It is a fusion powered propulsion device, it uses “heavy fusion technology” which can use any elements lighter than Fe-56 as power source. Is this design feasible?

After watching a video on YouTube, I recently became interested in the dynamics and physic's of why we aren't using electrical powered planes instead of burning thousands of fossil fuels every day. After doing a bit of my own research, I found the problem. When we increase the weight, we have to...

Hello all, I have been tasked with writing a very short article regarding the use of computers and software in early jet engine design up to modern times. I've been having a relatively hard time finding reading material through Google. I understand that modern jet engine designers use CAD...

So I'm starting to do some tests with nitinol (order about 5 feet of wire just to do some basic tests and get a feel for the material before I go any further). I've seen a few variations on different types of motors that are powered by nitinol and am wondering if they all have the same...

I'm interested in the knowledge that was available to aircraft engineers in the period 1900-1920. specifically the thermodynamics and mechanical engineering knowledge generally available, like in how much detail were the calculations on the performance, or the cooling of engines done, how...

The engine of a solar car I am designing(for my fictional stories but I would like a scientific point of view on this) is literally a DC circuit combined with mechanical force. First of all, there is a rechargeable battery. I would say it is about 24V fully charged. There are 2 wires coming off...

Hi, I've defined engine power requirements based on driving dynamics, but am not sure how to extend this to engine parameters. From design requirements, I've fixed my gear ratios, and hence can determine how much power and torque is required from the engine at a particular speed. I want to then...

hey i am engineering student i am interested in designing a ic engine. I want to know necessaries and parameters for designing a engine hey please provide some reference for it thank you:smile:

To give a little background I have machine tool training but not much other than what I have taught myself in general physics. Its a VERY interesting subject for me and I have thought about going back to college just to take a course or two relating to it. I come up with various ideas I would...

Hey Everyone, I'm a mechanical engineering student and I was wondering if there was any good book regarding IC Engine design; which includes timing belt design, camshaft, crankshaft, rocker-arm, pump design etc.. a whole in one package that design engineers use for designing ic engines...

I am thinking of building a Stirling engine and am debating between a gamma type and beta type. Any advice on which type I should go for, and what the advantages/disadvantages to each is? Thanks

Hi i would like to post for discussion my design of a new type internal combustion engine Please post your comments.The following information is to explain the description and operation. In drawing #1 The engine has three heavy pistons all attached together; two small and one large one in...

I wanted to ask about plasma propulsion engine. Plasma can be made by using radio waves. How this part of device looks like?(I know something, like an antenna, is used) I searched the net, but I didn't find anything. Thanks in advance. P.S Please explain as simple as you can

So, I've been working on an engine design that has been tried already, and nobody has really got it to work the way i think that it should. The engine I'm working with is a Wankel Rotary Engine and what I'm trying to do is make a modern, high-efficiency, high power-output diesel out of it. I'm...

Hey, I'm an electrical engineering student and I'm trying to design a solar dish which converts the heat from sunlight into electricity. I managed to make a small stirling engine with the results i got from google (The stirling engines made from coke cans). I was wondering how costly...

http://www.sciencedaily.com/releases/2008/09/080915164550.htm ScienceDaily (Sep. 15, 2008) — In an advance toward introduction of an amazing new kind of internal combustion engine, researchers in China are reporting development and use of a new and more accurate computer model to assess...

I have 10 weeks to complete a project on a Honda 5.5HP 4-stroke engine. The engine is for a kart. It is normally aspirated and has a sponge carb. I must do the following: (1) Examine the design/construction of the engine (2) Propose a new/modified design (3) Build (4) Test (5) Report This is...

Hello, I'm Arman, new user here. I'm a jet-engine designer and I'm really interested in building and running different types of jet engines. I have quetion now: Some amount of air enters a cone shaped pipe with a minimum diameter of 6 cm and a maximum diameter of 10 cm, and a length of 7 cm...

Hi there, I was wondering if you might be able to offer some proof or disproof on a theory for a new engine design that I am working on. We all know that steam as it condensates in a closed vessel creates a vacuum, so I am designing an engine which is designed to harness this natural...

I decided to try my hand at initiating a discussion. In particular, I'm interested in what others think about the rather novel (Brayton Cycle) engine design at (www.starrotor.com) and its claims? It's, in principle, the same type of continuous burn engine as in jet aircraft, but with somewhat...

I'm a junior attending an accelerated high school who's working on this year's science project. As of right now, I'm planning on building a liquid fuel rocket that is powered by gasoline with concentrated hydrogen peroxide acting as an oxidizer. I am currently working through the equations...

hey everyone i was wondering why people don't make an internal combustion engine in the shape of an A instead of a V. this way it would have two crankshafts, and two pistons and one cyliner head for every two pistons. I think this would make the explosion my effecitive than just one piston...
