Sentences with phrase «cylinder pressure»

Would an engine designed for pure ethanol (higher cylinder pressure etc.) not result in cleaner combustion?

With higher boost pressure comes increased horsepower, this means increased cylinder pressure.

And as you say, judging from the low cylinder pressure in this engine, there should be room for higher boost pressure.

Drivers who let their vehicles idle prevent the engine from reaching its optimal cylinder pressure and temperature causing a large amount of costly maintenance issues.

Also things such as incoming air temperature, engine core temperature (coolant), and, valve size are all factors in maintaining cylinder pressure.

Accordingly, small differences in the kernel formation rate or location may produce significant in - cylinder pressure variations [9].

To keep the reciprocating weight as low as possible, which enables this engine to scream to 10,400 rpm, the forged Wiseco pistons weigh just 260 grams and are supported by a set of 340 gram aluminum GRP «Pro Stock» connecting rods — producing some serious cylinder pressure with a 16:1 compression ratio.

Like turbos being more powerful and fuel efficient I believe (more cylinder pressure).

Leak Paths There are three major leak paths where cylinder pressure can escape: past the rings, the intake valve, or the exhaust valve.

The pressure test results you give (as long as the test was done correctly), shows a massive drop in cylinder pressure from where they should be.

Mazda has had to come up with some clever valve timing and injection strategies to enhance performance (not to mention the presence of two turbochargers), but the reduced cylinder pressures have enabled weight reduction and cost savings elsewhere in the engine.

Modifying components and install a largest intake manifold, larger diameter throttle bodies will have direct effect on the overall cylinder pressure.

Recently I've been looking into buying a higher PSI pressure transducer to do in cylinder pressure testing.

Compression Ratio: Increasing the mechanical compression ratio raises cylinder pressure, resulting in higher cylinder temperatures.

Higher cylinder pressure require a «hotter» spark with more current present to overcome the pressure and jump the gap from electrode to electrode in the spark plug.

High speed, piezo - resistive cylinder pressure sensors are integrated in the glow - plugs to acquire real - time data on combustion quality.

To take full advantage of the favorable combustion attributes and potential of E-85, the engine operates at diesel - like cylinder pressures and incorporates advanced spark - ignition technology.

The LT1 and LT4 use unique aluminum alloy pistons with a structure designed for the more intense cylinder pressures that come with forced induction.

The LT4 is based on the same Gen 5 small block foundation as the 6.2 L LT1 naturally - aspirated engine, incorporating several unique features designed to support its higher output and the greater cylinder pressures created by forced induction.

The Power Stroke V6 isn't the most lightweight engine on offer, having a block made of compacted - graphite iron rather than aluminum — a necessary trade - off given the diesel's higher peak cylinder pressures.

As effective as the magnesium / aluminum engine construction is for saving weight, the significantly increased loads and cylinder pressures of the N54 300 - hp engine required the use of an aluminum engine structure with cast - iron cylinder sleeves.

This issue is, you have serious cylinder pressure (or should I say, non-pressure) issues.

During part - load operation this cures the inherent drawbacks of large - displacement engines; namely inadequate filling of the cylinder, low cylinder pressure and greater friction, which in turn adversely affect efficiency and hence fuel consumption.

By using in - cylinder pressure sensors for the combustion control, the combustion process is perfectly optimised.

As the piston travels upward, abnormally high cylinder pressures may result in the mixture auto - igniting or detonating, which is why conservative compression ratios are used in consumer vehicles.

In cylinder pressure is in the 200 psi range.

Increasing the compression ratio further to take full advantage of the technology's cylinder - cooling effects would force too many other compromises, and with the current setup delivering 14 - bar peak cylinder pressures and 526 hp and 429 lb - ft, it just wasn't deemed worth the cost and effort.

What we see is the heads lifting due to cylinder pressure.

I have a similar tool and it works well although it can get tough to turn once the cylinder pressure builds up.

It basically gets down pulling a spark plug, getting that piston to Top Dead Center (TDC), threading the tester into the spark plug hole, hooking up compressed air (at a minimum pressure), bringing the cylinder pressure up to a set amount, and...

Pure Copper - Usually has a ring embedded within it at the cylinders to enclose the cylinder pressures.

It isn't oil consumption which is the problem, it's the fact you won't get the cylinder pressures you'd expect after ring seat of the compression rings.

I think the factor is cylinder pressure, meaning the accelerator is floored.

A low compression ratio of 14:1 minimizes peak cylinder pressures and reduces emissions, enabling the engine to meet regulations without the use of a urea after - treatment system.

@Mitsosp Not necessarily, the increased cylinder pressure can increase oil consumption, as explained in the link.

In a conventional two - stroke engine, the exhaust must open very early in the power stroke to enable the cylinder pressure to fall well below that of the incoming charge, in order to avoid spent gases entering the transfer ports and mixing with the fresh charge.

It basically gets down pulling a spark plug, getting that piston to Top Dead Center (TDC), threading the tester into the spark plug hole, hooking up compressed air (at a minimum pressure), bringing the cylinder pressure up to a set amount, and then watching how quickly it comes down again, and if it settles anywhere.

The cylinders are not scavenged of exhaust gases by the piston forcing them out, they simply escape because the outside air pressure is lower than the cylinder pressure after the spark ignites the fuel.
