Revving Up Efficiency: The Future of Engine Warm-Up in BMWs

Warm-Up: Does My Car Need It? Is warming up your car still necessary in the modern era?

People have been warming up their cars before driving ever since the first gasoline engines were invented. Some would argue that it’s a waste of time and gas, while others insist that it’s essential for longevity and performance.

So which is it? Let’s break down the reasons why cars need a warm-up and how BMW’s engine design could shorten its warm-up time.

Why Do Cars Need Warming Up? To understand the answer, we need to know how engines work.

Every car engine operates on the principle of combustion- a mixture of air and fuel igniting inside the engine’s cylinders, generating the force to turn the crankshaft. During cold weather, the engine’s parts such as the oil, coolant, and metal components will be affected, leading to the following challenges.

1. Thicker Oil

Engine oil is the lifeblood of your engine, preventing wear and tear, reducing friction, and dissipating heat.

However, when it’s cold outside, oil gets thicker, and it becomes challenging for the engine to move it around since it’s coagulated. Insufficient oil circulation will cause critical engine parts to remain dry, leading to unnecessary wear and even damage.

2. Condensation and Moisture Build-Up

When temperatures are cold, moisture can build up inside an engine.

These droplets can accumulate on the internal engine parts, leading to unwanted rust and corrosion. 3.

The Battery Struggle

In cold weather, batteries lose their ability to provide adequate power for starting an engine. This could result in difficulty starting the car or even complete inaction of the vehicle.

4. Metal Expansion and Contraction

It’s not just about what’s inside the engine and car.

It’s about how the car works as a whole. When it’s cold, metal contracts, and when it’s hot, it expands.

Weather changes can cause different materials to expand and contract at different rates, causing potential misalignment, grounding issues, or even a weakened car frame. BMW’s Engine Design and Warm-Up Time

While these are all valid reasons to warm up your car, let’s consider how BMW’s engine design impacts its warm-up time.
