Help to Identify some engine components ?

[Quebecker]

Hi,

Do some would be able to help me identify some components of the engine of my car. 2004 Civic EX 1.7 V-TEC

Part A-B and C ?





Part D ?





Part E ? (I think it's PCV Valve near oil filter)




Thank in advance

A: Idle air control valve.
B: Throttle position sensor.
C: Purge solenoid.
D: Crankcase vent return. NOT for the pvc valve, but to return to the air intake between the filter and the throttle body. On this model it has a hose directly to the air baffle that mounts on top of the throttle body!
E: Yes that is where the pcv valve is.

Hi Madsceintist

First thank you .... really appreciate

You seem to know this car so I have a question about the pcv valve. On a Hydrocarbon Cracking System forum, the guys say there is an vacuum effect (pressure) at the PCV valve outlet. I checked two times and there is no pressure at the outlet of the pcv valve.

I checked at the point where the tube from the pcv valve heads (intake manifold) and there is an effect of sucsion.

Doest it's possible ?

That should give you what you are looking for.

The blow-by gases are what escape from the piston rings from the combustion process. The swirling effect of the crank and the throwing of oil cause there to be small droplets of oil in the air as well which also are sucked into the intake. As this diagram is more like your car you can see that the air is sucked in the valve cover then through the engine. This IS NOT where you want to put the HHO !!! Use a different vacuum OR go between the pcv valve and the intake. You don't want the HHO to diminish and travel through the crankcase before it reaches the intake, AS well as the risk of detonation in the crankcase !!!!!!!!!!!!!!!!!

Here is where is my pcv valve





In fact, what I want, it's a place on the car that would allow me to generate pressure in my bubbler HCS

What you are not understanding is that that system IS NOT working off of pressure BUT vacuum! Both what you want and what you have ARE the same. The vacuum from the engines intake is what gives the PULL so that YOUR system will work!
The HCS adjuster is to regulate how much air to by-pass through the HCS system or back to the intake.

Right where the #7 is, is where you would want to tie into you system then back to where it is intended to be attached.

I know we passed this but [[vacuum effect (pressure)]] are counter active. You don't get any pressure from the pcv valve system unless your engine is worn badly and the piston rings are destroyed or broken, and the pcv system somewhere is stopped up. "IF" you don't have a vacuum at the intake where the valves hose is(intake side), then make sure the port isn't plugged with something. "IF" you have vacuum there and you don't from the pcv valve itself, change the valve. "IF" you still do not have a vacuum to the engine you could have a stopped up baffle that the pcv valve is in, which bolts to the block under the intake! The exploded view of the intake you have is very clear of all you need.
This is not as far fetched as it sounds but I had a car apart for some time and when I put it back together I could not figure out why I had a continuous code for egr valve solenoid,. Turns out a mud dobber bee had made a nest deep in the vacuum hose and it wasn't getting vacuum to the egr! I used carb cleaner and air to clear it. NO problem.
Stupid little things sometimes are a huge burden. Over-looking them is sometimes so simple.


Quick, simple test for you. With the engine running, take the oil cap off! Do you get pressure coming out of it? Does the hole suck a piece of paper to it? You should get NEITHER !! A proper running and sealed engine will not do one or the other!
Now pinch off the air hose from the valve cover to the intake tube! Now do you get a 'vacuum' at the oil cap? You should!
Let me know !!!!

Hi,

Always on my car, which one of this 2 vaccum is "venturi vaccum" (gentle at idle and increases with engine speed) ?

a) Intake Manifold Vacuum (from pcv valve to intake manifold)

b) Crankcase vent return vacuum (item D of fist page)

Thanks

The pcv valve has vacuum at all times, therefore the crankcase has vacuum all the time. The more throttle that you give the engine the less you will have a vacuum on ported lines, but there is always vacuum there. When the throttle is closed the vacuum increases in the intake, so it pulls more on the ported lines, but when you open the throttle, vacuum decreases on the ported lines(This is the reason that the cell set-up from the intake tube is best suited for the application). The vent for the crankcase to receive air is item D of the first page(this is where air goes into the crankcase). On your car there isn't a venturi type of port outside of the pcv port for what you are looking for, the evap port is in near the same spot also, so either could be used. It would not be beneficial to have the HHO go thru the crankcase before reaching the intake, nor is it safe!

This diagram shows you how changing the position of the port changes how much pull you can achieve. Unless you want to go into some serious work to make parts you will have to use what you have. Also it shows the narrowing of the inlet, as does the Cell I showed you in the drawing.

With the primary air-flow going thru the cell, you achieve a constant pull that you can adjust for air/fuel ratio, and your throttle is used just as it was designed for control of engine rpm.

I know b is the throtle positioning sensor? Thats the only one i know for sure. The pcv valve should be on top of the engine connected somehow to your valve cover. Thats what i know for sure from what i see not sure about the rest but you can always go to autozone.com and get some onfo about sensor location for your car there. Hope i helped.
