Ch. 75 Mass Air Flow Sensors Flashcards | Quizlet

Two technicians have different views on mass airflow (MAF) sensor contamination. Technician A states that at higher engine speeds near wide-open throttle (WOT), the contamination can cause the sensor to underestimate the amount of air entering the engine. Technician B states that the fuel system will go lean, causing spark knock and lack of power concerns when the sensor underestimates the amount of air entering the engine…

Upgrading to Gen III LS-Series PCM: Sensors and Inputs Guide

· The MAF sensor is used by the PCM to directly measure weight (or mass) of air that enters the engine to control fuel delivery. The MAF signal, measured in hertz (Hz), is interchangeable among the LT1 and LS1 sensors. The early 1985–1989 TPI MAF sensor is not compatible with the LS-series PCM. In fact, the Gen IV MAF sensors are also compatible with the LT1 and Gen III PCMs.

Understanding a car air intake system -

A modern car air intake system has three main parts - the air filter, mass flow sensor and throttle body. Located directly behind the front grille, the air intake system draws air through a long plastic tube going into the air filter housing, which will be mixed with the car fuel. Only then will the air be sent to the intake manifold that supplies the fuel/air mixture to the engine cylinders.

How car heating and ventilation systems work | How a Car Works

Modern cars are designed to have a constant through-flow of fresh air that keeps the interior atmosphere pleasant even with all the windows shut. The incoming air can be heated by the engine to keep the windows clear of mist and the car interior at a chosen temperature. Air flow Air enters a large duct at the front of the car, placed so that when the car is moving the entry point is in a high ...

How does a carburetor work? - Explain that Stuff

· How engines burn fuel. Engines are mechanical things, but they're chemical things too: they're designed around a chemical reaction called combustion: when you burn fuel in air, you release heat energy and produce carbon dioxide and water as waste products. To burn fuel efficiently, you have to use plenty of air. That applies just as much to a car engine as to a candle, an outdoor campfire, or ...

Volumetric Efficiency and Engine Airflow -

· The actual volumet of air the engine ingests compared to the theoretical maximum volume is called volumetric efficiency (VE). An engine operating at 100% VE is ingesting its total displacement every two crankshaft revolutions. There are several factors which determine the torque an engine can produce and the RPM at which the maximum torque occurs. However, the fundamental determinant is …

The Air Intake System: How It Works - LiveAbout

· The cold-air intake tube marks the beginning of air’s passage through the air intake system, the only opening through which air can enter. Air from outside the engine bay is typically lower in temperature and denser, therefore richer in oxygen, which is better for combustion, power output, and engine efficiency. Engine Air Filter . The air then passes through the engine air filter, usually ...

Basic - Garrett Motion

After passing through the intake manifold (4), the air enters the engine’s cylinders, which contain a fixed volume. Since the air is at elevated density, each cylinder can draw in an increased mass flow rate of air. Higher air mass flow rate allows a higher fuel flow rate (with similar air/fuel ratio). Combusting more fuel results in more power being produced for a given size or displacement ...

How to Find and Repair Automotive Engine Backfires

· Your vehicle's computer system monitors the air that enters the engine via the mass air flow sensor. When this sensor malfunctions due to a condition called coking the hot wire inside the sensor becomes contaminated and will alter the reading to the computer which will create a lean mixture condition that may or may not trigger a check engine light. The lean condition is because the …

One side of the turbocharger, the impeller side, is connected to the engine’s air intake. Without a functional air filter, dirt and debris can easily enter the turbocharger, causing extreme damage. To make things worse, metal from the failed turbocharger can find its way into the engine, circulating throughout the system. This can result in complete engine failure. • Internal engine damage ...
