While often overlooked in comparison to the compressor, the accumulator also plays a critical role in maintaining the A/C system's health, serving as an equalizer and reservoir for the refrigerant and oil necessary to protect the compressor. In fact, just think of it as the compressor's personal bodyguard.
Same as the accumulator dehydrator, the receiver drier is the compressor's watchguard, making sure it has enough refrigerant and oil circulating throughout the system for optimal performance. The only difference from the AD? Where it is located in the A/C system flow and the vehicle application
A customer calls because they're boiling. Or freezing. And definitely unhappy. So replace that broken blower motor with a new Delphi quality one. That way you can really take it for granted.
Even while inside a vehicle, we are bombarded with air impurities. Pollen. Toxins. Skunk. Use Delphi air filters, and your customers won't have to worry about these things. Or smell them.
Delphi charge air coolers are specifically designed to keep a car's powertrain running at optimal temperatures. And that means satisfied customers who are sure to keep their cool.
No extra parts to purchase or stock. Sealing washers included with all compressors (when applicable). Our compressors are leak tested to one pound of refrigerant in 40 years using sophisticated mass spectrometer leak test equipment.
Delphi covers more than 3,400 applications. Delphi supplies compressors for 1989 to present applications. Delphi provides HVAC components to eight of the top 11 OEM global manufacturers. The majority of Delphi compressors are made in North America. Delphi manufactured the first underhood air conditioning system in 1954.
Delphi condensers are OE engineered to be so efficiently cool, they're in charge of reducing refrigerant temperature so the entire AC system chills out.
How a vehicle stops is just as important as how it moves. Today our OE safety expertise is fitted to millions of vehicles worldwide. With innovative technologies such as adaptive cruise control, electronic scanning radar, lane departure warning and collision mitigation we are committed to helping stop traffic accidents before they happen. These systems are all designed to support Delphi’s vision of a society with zero fatalities, zero injuries and zero accidents.
The same is true in the aftermarket. That’s why we offer a range of parts designed, engineered and manufactured to OE standards. But not just that. As vehicles have become more sophisticated, so too has the technology needed to diagnose and service them. In addition to parts, this means diagnostics and expert knowledge are now part of most routine brake jobs. Delphi offers all this…and more.
It's safe to say our ABS sensors are pretty direct. They don't hesitate to apply pressure where it's needed. But they're ready to relieve pressure, too. No mixed signals here.
Without question, brakes are the most powerful, and important, system on your vehicle. The mechanical and thermal stresses acting on the brake disc itself are extremely high. For this reason it’s imperative they’re up to the job, and perform just as they’re intended. Like all our braking product, our discs are made to mirror the OE. That’s why if the OE disc has it, the Delphi disc has it too. Be it coated, cross drilled or high-carbon…it’s a given. So whatever the technology, you can be assured that every Delphi disc has been designed, engineered and manufactured to provide the very best braking performance. Just like the OE.
Techs make great detectives. Ever had a hunch that a hose was the problem? Next time, you can scratch off hoses from your suspect list when you choose high quality hoses from Delphi.
Responsible for stopping vehicles quicker and quieter than ever before, brake pads are one of the most important components in the braking system. And is why there’s no compromise when it comes to choosing one. As a leading Tier-1 OE manufacturer, our pads are designed, manufactured and tested to the meet the same standards of performance, consistency and longevity as the OE. We call it Delphi’s “Five Layers of Quality”… and we build these into every one of our pads.
Delphi fuel parts aren’t just high quality, they’re Delphi quality. Put over 100 years of under-the-hood experience into every part make, so they deliver 100% satisfaction for you and your customers.
Gunk. Shmutz. Goo. Dirt means damage to a diesel fuel injection system, so Delphi filtration products have been OE designed to block even the tiniest bits of yuck, crud and who-knows-what.
Bring on the cold starts. With more than 30 years of fuel injector engineering and manufacturing experience for the world’s largest automakers, extreme temps from -40°F to 230°F are no big deal. Which means can take the heat, too.
When it comes to building fuel modules, Delphi applies its OE heritage and technological leadership to deliver the highest level of performance and customer satisfaction. Delphi engineers each fuel module with the same stringent standards apply to the parts make for Chrysler, Ford, GM and other OEMs. Carry fuel pumps, modules and hanger/sender assemblies for more than 98% of vehicles in North America.
Precision is key for the fuel pressure regulator on any vehicle. So when you need to pick a replacement part, choose Delphi — the brand that’s been OE engineered to perform consistently. Test fuel pumps for performance and durability, and use results to make better parts. That’s why Delphi holds more than 30 OE-proprietary innovations and 150 patents in fuel module and pump design.
Those smart designs, and rigorous testing and troubleshooting, have helped us create fuel pressure regulators and other fuel components that pass the tests of time, emissions standards and customer satisfaction.
A fuel pressure regulator works to maintain proper and consistent pressure for the injectors during a variety of driving conditions. Pressure that is too high can cause misfiring and increase vehicle emissions. Low pressure can cause poor vehicle performance and slow — or no — starts. Both high and low pressure can reduce fuel efficiency and even shorten the life of the engine. A leaky fuel pressure regulator diaphragm often causes lower fuel pressures, but the problem can be tricky to diagnose. Regulator issues are often misdiagnosed as an oxygen sensor problem, and can cause multiple, misleading OBD II codes.
Vehicle manufacturers have relocated fuel pressure regulators from the fuel rail in the engine compartment to the tank, which keeps fuel temperatures lower and cars running more efficiently. OE design enhances fuel control accuracy for smooth driving and emissions performance that will keep your customers happy. Delphi uses exclusive NitrileTM nylon fabric diaphragms, which are strong and resilient against corrosive, high-ethanol fuels.
Delphi fuel pressure regulators are available in two different designs--universal pressure and mini-cartridge pressure--for wide coverage of domestic vehicles on the road today.
All Delphi mini-cartridge regulators are 100% flow tested and the pressures are factory calibrated. Six Delphi mini-cartridge part numbers represent more than half the sales volume on GM applications, which helps streamline your inventory and reduce your investment.
Crank the engine. Push the button. Delphi ignition coils help to make sure a driver is good to go. But thanks to our OE experience, these parts also help a car maintain tighter control over emissions, fuel economy and performance.
Help ensure fast starts, consistent engine performance and optimized fuel efficiency with Delphi ignition coils. Delphi makes more than 10 million ignition coils for North America each year, and each one is engineered to OE design specifications for vehicles from Ford, Toyota, Nissan, Lexus, GM, Mazda, Subaru, Acura and more.
Delphi has analyzed the tough environment that ignition coils must withstand and discovered how vibration, temperature changes and even the failure of other components, such as spark plugs, can cause ignition coils to fail.
Specifically, these stresses can cause ignition coil wiring to break or have shorts. The insulation inside the ignition coil could also fail and cause energy to escape. Delphi is combatting these issues with an innovative design and high-quality materials.
Delphi ignition coils are designed—and endurance tested—to resist the common stresses that cause failure.
The result is an efficient coil design that ensures the power in the coil has a streamlined path to the spark plug. This design also reduces the occurrence of shorts inside the ignition coil.
A Mass Airflow (MAF) sensor, also known as an “air meter,” measures the air coming into the intake system and transmits this information to the ECM. The ECM utilizes the MAF sensor output signal to precisely schedule fuel injection, creating an optimal air-fuel ratio. This results in reduced emissions and improved fuel economy, all while maintaining drivability. Delphi MAF sensor designs provide low restriction air measurement for increased horsepower.
MAF sensors can be installed two ways: as a complete unit including the flow tube or as a probe-only design, which provides a greener, more cost-effective and often faster option.
Contamination is a key reason why MAF sensors fail and require replacement. As air, dirt and other debris get into the sensor, the parts become contaminated and fail. Drivers often notice sluggish performance, rough idling or even stalling. There may also be a more frequent need to refuel.
You won’t find any remanufactured MAF sensors in a Delphi box. Even better, all parts are tested and calibrated to OE standards using highly accurate OE equipment. By testing to OE specifications, Delphi helps ensure that the sensors provide accurate readings and airflow output, which helps to reduce comebacks.
Remember, many remanufactured MAFs are simply cleaned and tested, so all debris or contamination on the sensor may not be completely eliminated. Because of this, the ECM could still receive inaccurate readings and the vehicle may still experience sluggish performance.
Certain Delphi MAF sensors feature dual heated elements, allowing any platform to incorporate our MAF sensors into its air/ fuel system, regardless of ducting assembly.
The Manifold Pressure Sensor is used in an engine's electronic control system. Engines that use a pressure sensor are typically fuel injected. The sensor provides instant manifold pressure information to the engine's electronic control unit. The data is used to calculate air density and determine the engine's air mass flow rate, which in turn determines the required fuel delivery for perfect combustion. A fuel-injected engine may use a MAF sensor or a Pressure sensor-- or sometimes even both-- to detect the intake airflow.
The Manifold Pressure Sensor can be used for diagnostics as it measures the throttle performance, turbo performance and can be used to detect leaks in the inlet manifold. Because of its position it should always read a negative pressure unless the turbo charger is boosting pressure. This can be seen in the attached diagram.
