Proposition 65 requires businesses to notify Californians about significant amounts of chemicals in the products they purchase. Please see the California state government official website for more information: California Proposition Proposition 65 entitles California consumers to warnings for products that contain chemicals known to California to cause cancer and birth defects or other reproductive harm if those products expose consumers to such chemicals above certain threshold levels.

Additionally, for certain products sold on AESwave, we also provide the following warnings based upon California law:. WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm.

Some examples of these chemicals are:. Your risk from exposure to these chemicals varies, depending on how often you do this type of work. To reduce your exposure, work in a well-ventilated area and with approved safety equipment, such as dust masks that are specially designed to filter out microscopic particles.

Duramax engines are not designed and produced by the manufacturer that sells them. This means that the people who created the engine management and emissions systems and the people who wrote the repair information didn't always understand each other.

Repair information is becoming scarce and inconsistent for all vehicles, but is even worse for these Bosch fuel systems, Isuzu-designed engines, and GM vehicles. ATG spent months collecting and comparing technical information to fill in the holes of the repair information, and then diagnosed and repaired these engine management and emissions systems to validate everything we found.

Add to Wish List. Print Page.Though not the first electrically controlled diesel in the light-duty market the Ford 7. It boasts four-valve aluminum cylinder heads, excellent component packaging, and a reputation for durability, power, fuel economy, low combustion noise, and very little vibration.

Ironically, this high-tech engine exists due to the government-mandated emissions standards that required a percent reduction in tailpipe discharge from previous mechanically fueled designs. Thus, gasoline-style engine management was required to tame and improve upon the diesel engine. The Diesel Combustion Challenge There are three basic stages of diesel combustion that take place inside a direct-injection diesel engine-delay, uncontrolled combustion, and controlled combustion.

These three stages are defined as follows:. Delay: Diesel fuel is sprayed into the compressed air charge in the cylinder and waits for the temperature to reach 1, degrees F to ignite. Uncontrolled combustion: The injected diesel fuel then burns very rapidly in a rogue manner, much like detonation in a gasoline engine. This creates the diesel clatter. Controlled combustion: The additional diesel fuel burns at the rate it is injected into the cylinder.

High-Tech Duramax Solution To achieve the desired emissions, noise, and vibration goals, the uncontrolled combustion stage needed to be minimized or eliminated. This could only be done through electronic control of the injector and an extremely high-pressure fuel source. In aam ke nuksan case of the Duramax, GM uses a Bosch common-rail fuel system. The intent was to eliminate or at least minimize the central core of a mechanical injector spray pattern that would evoke the uncontrolled combustion event until a reaction zone where the heat from the burned fuel travels into the unburned fuel could be established.

Recognizing the need for the enthusiast to understand how electronic common-rail diesel engines operate, Diesel Power attended the General Motors Training Center in Ardsley, New York, to learn about the Duramax diesel engine. The Four Different Duramax Engines The Duramax has been produced in four different versions, and each version gets its name from its engine code.

The engine models break down by the following codes, model years, and VIN numerals:. Though there were evolutionary changes over the years to the engine and controls, most basic component functions stayed the same. Then came the LBZ in and it featured a lower compression ratio, higher injection pressure, and an improved engine block design.

Control Strategy The Duramax engine uses the following components to control the injection system. Input sensors monitor operating conditions of the engine and inputs from the driver. These inputs are sent to the engine control module ECMwhich processes sensor inputs and generates electrical output signals that get sent to the actuators that operate the engine. Mass Air Flow MAF sensor: Mounted on the intake air assembly, it measures the volume of intake air for fuel delivery calculations.

Intake Air Temperature 2 IAT 2 sensor 'and-newer applications : Located in the intake manifold, this sensor is used to measure post-turbocharger intake air temperature. Camshaft position CMP sensor: Located at the front engine cover, teucrium nasal drops one provides a 3X signal to identify piston position.

Barometric sensor ''05 applications : Found on the left valve cover, it identifies barometric pressure for the ECM. The air pressure reading is used to fine-tune the fuel supply. Low Oil Level Switch: Mounted in the oil pan, it identifies when the oil level is low. Brake Switch: This instrument provides an input to the ECM used for fuel delivery and cruise control.

Acceleration Pedal Position APP sensor: Made up of three individual sensors in one housing, it is mounted on the throttle pedal assembly. Each of the three sensors has a unique range of operation so that sufficient resolution is created for accurate throttle input.

This is accomplished by altering the pressure and direction of engine oil acting on either side of a hydraulic piston. The piston has a rack of teeth that engage the pinion teeth of a cam. Piston movement causes the cam to rotate and pivot the vanes in the turbocharger.Here you will find useful basic information and important tips relating to the intake-air temperature sensor in vehicles.

The intake-air temperature sensor might be a fairly unassuming component, but it plays a key role. Its task is to supply the engine control unit with an important measurement for correcting the mixture formation and the ignition. This page explains the functional principle of the intake-air temperature sensor, the effect of faults, and what could cause the sensor to fail.

You will also find step-by-step instructions on how to check the sensor. The intake-air temperature sensor determines the temperature in the suction pipe and forwards the voltage signals arising from the temperature to the control unit. This evaluates the signals and influences the mixture formation and the firing angle. The resistance of the temperature sensor changes depending on the intake-air temperature. As the temperature increases, the resistance is reduced, which reduces the voltage at the sensor.

The control unit evaluates these voltage values, since they are directly related to the intake-air temperature low temperatures result in high voltage values at the sensor, and high temperatures result in low voltage values. A faulty intake-air temperature sensor can manifest itself in different ways through fault detection by the control unit and the resulting emergency program strategy.

The internal resistance of the sensor is determined. The resistance is temperature-dependent. When the engine is cold it is high-impedance, and when the engine is hot it is low-impedance. Check the wiring to the control unit by checking continuity and short circuit to frame for every wire to the control unit plug. Check the supply voltage at the removed sensor plug using the voltmeter. This is done with the control unit plugged in and the ignition turned on.

Reference value: approx. If the voltage value is not reached, the voltage supply of the control unit and the ground supply must be checked according to the circuit diagram.

If these are OK, a control unit fault comes into question. UK Newsletter Video Hella team. Toggle navigation. Home Technical.
