How does egr valve reduce combustion temperatures?
The Exhaust Gas Recirculation (EGR) valve reduces combustion temperatures by recirculating a portion of the engine's exhaust gases back into the intake manifold. This process dilutes the air-fuel mixture, lowering the overall oxygen concentration in the combustion chamber. As a result, the peak combustion temperatures decrease, which helps reduce the formation of nitrogen oxides (NOx) and improves overall engine efficiency. By controlling combustion temperatures, the EGR system contributes to lower emissions and enhanced engine performance.
If there was a large fall in the air temperature around the cylinder what effect would this have on the flame of the camping stove?
A large drop in air temperature around the cylinder would likely cause the flame of the camping stove to diminish or even extinguish. This is because lower temperatures can reduce the efficiency of combustion by causing a decrease in the vaporization of the fuel and its mixing with air. Additionally, cooler air can lead to a decrease in the flame's temperature, affecting its stability and intensity.
If a firms fixed financial costs decrease the firms operating breakeven point will do what?
decrease <--------WRONG!!!!! The operating breakeven point will remain unchanged.
Do particles increase or decrease at cold temperatures in a balloon?
Particles in a balloon decrease at cold temperatures because the gas inside the balloon contracts as it cools down, resulting in a decrease in volume and therefore a decrease in the number of gas particles.
Gasoline is burned in the combustion chamber of a car the reaction rate is what?
decrease
What is the sensor on the right cylinder head?
It could possibly be the Cylinder Head Temperature Sensor (CHTS) which monitors the temperature of the coolant/water circulating through the cylinder head, and tells the computer to increase or decrease the injector spray length. Warmer temperatures = shorter sprays of fuel from injectors, and vice versa. -Anthony C.
What is an oil control ring and its function?
An internal combustion engine has pistons that slide up and down in each cylinder. They do this very rapidly and need oil for lubrication to prevent melting the cylinder walls. An O-ring is a slim metal piece that surrounds the head of the piston and prevents oil from getting above the piston and being burned in the combustion chamber. This is a good thing, as the supply of oil will not decrease so quickly. This also reduces unpleasant exhaust gases and prevents the combustion gases from contaminating the oil.
If decrease in income taxes payable cash flow will be?
If there is decrease in income tax payable amount it will reduce the cash flow from operating activities or cash outflow from operating activity.
How does remover of thermostat effect fuel?
Removing the thermostat from a vehicle can lead to engine overheating and inefficient fuel combustion. Without the thermostat, the engine may not reach its optimal operating temperature, causing it to run richer in fuel mixture, which can decrease fuel efficiency. Additionally, prolonged running at suboptimal temperatures can lead to increased engine wear and potential damage, further impacting fuel consumption and overall performance.
What happens as a piston goes down?
As a piston moves down in a cylinder, the volume inside the cylinder increases, which causes a decrease in pressure according to Boyle's Law. This movement typically allows an intake of air or fuel mixture in combustion engines or creates a vacuum in other applications. The downward motion can also help in drawing in the necessary fluids for the next cycle. Additionally, in a combustion engine, this phase is part of the intake stroke, preparing for the compression stroke that follows.
Operating leverage results from what?
Operating leverage generally refers to revenues growing faster than expenses. This would be positive leverage. Companies with a largely fixed expense base have a lot of operating leverage (in both directions). If revenues are growing but expenses are flat, operating margins increase (positive operating leverage). If revenues decrease while expenses remain flat, operating margins decrease (negative operating leverage).
Do temperatures increase or decrease when a storm is coming?
Temperatures can vary before a storm. In some cases, temperatures may rise as warm air is brought ahead of the storm system. In other cases, temperatures may drop as cold air is displaced by the storm. It depends on the type of storm and its characteristics.
