Hybrid Engines: Advanced Technology That Requires Specialized Protection

The world of mobility is changing rapidly, and hybrid powertrains are at its heart. But what does driving a hybrid car really mean, and why is lubrication so crucial?

Today, a state-of-the-art repair shop must deal with two different types of “hybrid vehicles,” each with specific lubrication requirements:

1. Bifuel Vehicles (Gasoline + LPG/Natural Gas)

Often incorrectly referred to as hybrids, these are internal combustion engines that use two different fuels. The combustion of these gases (LPG or natural gas) occurs at higher temperatures and produces dry residues. In this case, the lubricant must have extremely high thermal stability to protect the valves and valve seats from premature wear.

2. Hybrid Electric Vehicles (HEV / PHEV)

This is true “parallel” hybrid technology, in which an internal combustion engine and an electric motor work in tandem on the same crankshaft. In these vehicles, the electric motor handles the most critical phases (starting, acceleration, and regenerative braking).

How the Parallel Hybrid System Works

The most common configuration in the automotive industry is the parallel hybrid, in which the internal combustion engine and the electric motor work together to transmit power to the same crankshaft.

The unique feature of this system lies in its load management:

• Electric mode: Acceleration from a standstill, rapid acceleration, and braking (the situations where the most energy is consumed) are handled by the electric motor.
• Thermal mode: The internal combustion engine engages only when necessary.

Although this system drastically reduces fuel consumption and emissions, it subjects the internal combustion engine to a unique form of mechanical stress: the constant cycling on and off (frequent start-stop cycles) prevents the engine from maintaining a constant temperature, increasing the risk of wear.

Why choose a specialized lubricant?

In hybrid engines, the lubricant must be extremely fluid so that it can instantly reach all moving metal parts, even at low temperatures.

Motul, a long-standing pioneer in technological innovation, has developed a range specifically designed for hybrid vehicles. These lubricants are formulated to ensure:

1. Immediate protection every time the engine is restarted.
2. Reduced friction to maximize fuel efficiency.
3. Controls deposits, keeping the engine clean longer.
