tl dr: By adding a throttle plate, it creates the vacuum needed to draw in gasses from an EGR valve.
Since diesel engines are designed to run lean, they don't need throttle plates to run. They utilize the amount of diesel fuel needed to keep the engine running and to provide the work needed to do the job required of them. One of the inherent issues with ...
There are trade offs, so no clear answer here.
First of all, just to be anal and clear something up ... what you have is actually a 4-ring and a 5-ring piston. The oil control ring at the bottom actually consists of two rings and a spacer.
The main trade off is, the 4-ring piston will have less drag on the cylinder walls, but the 5-ring piston will seal ...
A "Z" frame refers to a modification done to what would otherwise be a straight framed vehicle. Here is an image of two frames (done via 3D printing) of what the difference would be:
the idea is to take the straight frame (top) and make the zig-zag in it. This in effect, lowers the body closer to the road without having to drastically alter the ...
Yes, there are a few
Zero Motorcycles have quite a few models that are available for purchase right now. They are up to 67HP and a 197 mile range.
Harley Davidson has a model that should be released soon. They are touring the country with them and allowing people to test drive them at the moment while they further develop their technology.
I would ...
The general area could be called the "nose" of the vehicle.
Depending on the vehicle's design, the logo may be found on the bonnet/front hood, front grille or front fender.
Bonnet, BMW i8
Grille, Mercedes G Wagon
Front Fender & Grille, Maserati Ghibli
There are three considerations when making a low end/small capacity engine
2 and 3 directly affect 1.
To make a gearbox more reliable you need to make the parts more durable, this is normally achieved by using more materials or more robust materials which add to the cost.
To make a 6 speed gearbox fit in the same space ...
Anti Shudder Valve
Not a direct answer, but one engine component that many people confuse with a throttle plate on a diesel engine is called an "anti shudder valve". This looks exactly like a throttle body, but it only has two positions - fully open and fully closed.
On an engine equipped with the device, the valve is completely closed when the key is ...
Once you have driven a few cars for a while you will get used to knowing from walking up to a car and getting in just how big it is. But until that time you can use some useful tricks:
parallax: if you really want to get a good idea of distance, move your head from left to right to see how much a point on the object in front moves compared to a reference ...
I don't believe there is a special placement in consumer vehicles. Most are designed with space in mind and ease of servicing. With the energy being transferred from the spinning rotor to the stationary brake system, the force would likely be the same from any clock position the caliper is in. Therefore, position probably isn't as critical.
Is this a good idea for a car?
I'll cut to the chase - No, it's a crap idea.
It's not like a car where there's all kind of ridiculous connections that can all go bad and where the chances of 1 thing goin bad out of infinite things is 100%.
You see the majority of the complexity that you so charmingly dismiss as "all kind of ridiculous connections&...
Most "dual" exhausts aren't true dual exhausts. They are dual tipped exhausts. This means there's one pipe coming back from the engine, then feeds into a muffler and then out to two separate tips. Usually, there's less back pressure on one side than there is the other. The exhaust follows the path of least resistance.
If they are true dual exhausts, they ...
As said in the other answers, each car is different, and it's mostly experience, if you don't have these little electronic helpers.
But I have one trick: Watch the light cones of your front light. As you move towards a wall or an other car, the cones become smaller and smaller, until they are ultimately as wide as your lights. So the width of the light cone ...
Every single car is different, most of them have different steering angle, different turn radius, etc. So it's all about getting used to it.
But sometimes it doesn't work, especially on a long base comfortable cars, that's why designers invented parking sensors...
Many urban cars (small and maneuvrable) if you look from the top, they have really round ...
In addition to Zero and Harley there's Brammo. Due to their light weight electric motorcycles compare better as far as range their Internal combustion counterparts than electric cars do. Most will do >100 miles per charge, conventional bikes usually do 100 to 200 miles. Electric motorcycles have managed a 100 mph lap of the 37.75 mile Isle of Man course.
You assume that the piston fully retracts into the caliper when you release the brake. But that's not true.
When the pad wears, it becomes thinner, and the piston moves out to compensate. But when the brake is released, the piston retracts only a little, just enough to remove the pressure from the pad. You can't even see it.
When the pads are replaced, the ...
What is the purpose of this design?
Judging by some other Honda Beat images online, it looks like its primary purpose is to protect the internals from the rear wheel slinging mud.
It makes more sense to just fully isolate the inner engine parts from mud and rain instead of having this flimsy cover as protection.
It does make more sense, but other ...
Credit to @Andrew Morton for this answer; which he is happy for me to submit.
I simply used PA Soft to disable the checks in the Light Control Module (LCM) by going into "module coding" (or similar?) and unchecking the checks, then writing the coding data to the module. Make sure you read the coding data from the module first!
Consequentially, this means ...
Another option is to find a hardened sleeve that goes through the frame and hole with a smaller diameter bolt that is just to hold it in place.
The orange bit is the sleeve, then as long as there is sufficient thread on the bolt to clamp it will work. You can make the sleeve thicker and only use a 4mm or 5mm diameter bolt...
Here's a rather obscure topic to focus on, but still relevant; Clamps. Considering which type of clamps you're going to use is necessary based on what material(s) are present in the cooling system. If you have Plastic Water-necks, or anything plastic involved, you're going to need a Constant-Tension style Clamp. Using a Worm-Style Clamp will result in the ...
Yes, Zero Motorcycle for one. They had several at the last Harley Davidson show up in Phoenix Arizona.
These things are fast!
And very good range.
Just do not make the sound of a Harley.
They told us at the demo, that there are a few actually used by a couple of police departments.
With today's car designs, you need to "know where your corners are." Blind spots are preventing you from seeing how much space you really do have immediately around your vehicle, so you need to imagine, based on previous experience, how does an object look like when it's far enough away.
It is possible to have a vehicle design where you can actually see how ...
