“Synthetics in TGDI engines operate hotter than traditional engine designs and greatly benefit from Pennzoil synthetics with Pureplus® technology.”

Shannon Simmons, Shell Lubricants Technical Advisor

Hotter Conditions

Smaller turbocharged engines need to work harder and at greater temperatures. These additional stresses on the oil make it more susceptible to evaporation, thermal degradation, and oxidation.

For this reason, Pennzoil Platinum® Full Synthetic motor oil with PurePlus® Technology is strongly recommended for use in turbocharged engines, as it is far more resistant to damaging high temperature degradation.

Low Speed, High Torque

Another potential problem with TGDI technology is a phenomenon known as ‘Low Speed Pre-ignition’ or LSPI. This occurs when low engine speed is coupled with high torque, resulting in abnormal combustion events that can lead to serious engine damage.

By using high quality synthetics, like Pennzoil Platinum® Full Synthetic motor oil with PurePlus® Technology, TGDI engines can safely maintain their efficiency and fuel economy performance.

Wear & Corrosion

Direct fuel injection also places significant demands upon the motor oil. All too often, small amounts of the injected fuel cannot fully evaporate due the short time interval between injection and combustion, leading to fuel wetting the cylinder liners and piston tops. From here, fuel can find its way into the sump, potentially accelerating oxidation and acid corrosion within the engine. Direct injection can also lead to higher levels of soot formation, which is highly abrasive and leads to component wear, particularly in the valve train. The oil is designed to hold soot (produced by the combustion process) in suspension and away from vulnerable engine parts. However, inevitably this leads to increased levels of acidity and oxidation within the oil, compromising the ability for low quality oils to lubricate effectively. This is yet another reason Pennzoil Platinum® Full Synthetic motor oil with PurePlus® Technology is strongly recommended for use in turbocharged engines, because no other leading motor oil provides better protection from friction3.

Challenge to Industry

The automotive industry is under going a period of exceptional technological development, driven in part by increasingly stringent fuel economy standards and increased emissions targets.

To address these challenges, car manufacturers have channeled unprecedented levels of resources into research and development.

The goal is to develop breakthrough technologies that will deliver outstanding performance and efficiency in desirable, safe, and durable vehicles, with the least possible additional production cost.

Turbo Boost

To address this issue, a turbocharger is tied to the engine to boost power output– turbochargers work by compressing hot exhaust gases through a turbine that can reach over 200,000 RPM, forcing pressurized air into the combustion chambers. The increased airflow allows more fuel to be injected and higher output achieved, enabling the driver to enjoy the fuel economy benefits associated with a smaller engine, combined with the power and performance of a larger engine when required.

Direct Injection & Precision

Gasoline direct injection technology allows the injection of fuel to exactly where required—the combustion chamber. Here, the fuel is mixed with air and as it evaporates it cools the charge, reducing the chance of engine knock, while enabling operation at much higher compression ratios. This improves the torque and efficiency of the engine. With the addition of gasoline direct injection technology, the result is a compact, fuel efficient and high output engine.

Modern TGDI engines feature many other fuel saving technologies that include—Variable Valve Timing (VVT), providing precision control of air into the engine; variable flow oil pumps that deliver the precise amount of oil to exactly where it is needed; and special coatings to liners and key components that reduce internal friction and further improve fuel economy.

A New Era

Evolution in engine design is driving a new era of innovation and development in oil technology. The lubricants industry is leading the way by embracing the challenges, formulating new tests, and setting new oil specifications that will continue to protect TGDI engines well into the future. Specifically, oils are being adapted to enhance turbocharger performance, reduce engine wear, and provide greater resilience to soot formation. Sophisticated additives that are blended with the oil help to mitigate the effects of LSPI, limiting damage to the engine caused by abnormal combustion events whilst maintaining engine performance. Pennzoil Synthetics with PurePlus® Technology are appreciably less prone to evaporation and more resistant to high temperature degradation and oxidation caused by the combustion process. In short, synthetic motor oil is a key enabler of TGDI engine evolution. It is essential to the delivery of superior fuel economy and unlocks opportunities to develop even lower viscosity oils that simply would not be possible with conventional oil technology.

Today’s fuel economy and emissions regulation has a huge impact on vehicle technology and this is only the beginning. With vehicle development for 2020 and even 2025 already underway, we can expect to experience greater pressure on the industry to forge ahead with breakthrough technologies that will meet all future emission and fuel economy targets. As engine technology continues to evolve, synthetic motor oils will play an increasingly critical role in meeting these targets. New generations of ultra-low viscosity oils are already in development and will be a vital component in the quest for greater durability, improved efficiency, and increased fuel economy.
“Motor oil is really important in a turbocharged engine because of the extra thermal stress that the turbo bearings see with the hot exhaust gases running through the turbo.”
