Making 1,000 HP With Tiny F1 Engines

Turbocharged Electric Motors: Wizardry of High Thermal Efficiency
How Tiny Formula 1 Engines Make 1000 HP!

A 1,000-horsepower engine is no longer as remarkable as it once was. You can purchase a production vehicle that produces such an amount of power with either an electric or petrol motor. Through Chrysler’s Direct Connection, you can procure a crate engine with a staggering 1,000 horsepower. Yet to manufacture this power using a mere 1.6-liter engine feels nothing short of miraculous.

Leave it up to Jason Fenske of Engineering Explained to break down the mystery surrounding these tiny powerhouses. As Fenske points out, much of the credit goes to the combination of a 1.6-litre turbocharged V6 engine that can rev at unprecedented speeds coupled with two electric motors.

The root of the contemporary motor models can be traced back to 2014 when the FIA, the ruling organism of Formula 1, produced the details for the motor. A piece of those features included the use of turbocharging combined with two electric engines and a battery as a reserve of energy. Different from the Toyota Prius hybrid vehicle meant to promote fuel efficiency, the combination in an F1 car works to increase force.

An electric motor is used to control the turbocharger instead of a wastegate, as well as for regenerative braking. The energy acquired from these operations is stowed in a battery, which is utilized to supply power to a secondary motor hooked up to the crankshaft. This whole combination is referred to as the Energy Recovery System (ERS), delivering an extra 160 horsepower and able to be activated for brief moments when accelerating or passing another vehicle.

The internal-combustion engine alone produces an extraordinary 830 horsepower, which is very impressive considering the size of these engines. Another remarkable feature is their fuel efficiency. Taking into account security, F1 cars aren’t permitted to refuel during a race, implying they must carry sufficient fuel to last around 250 miles. Moreover, according to F1 regulations, the vehicles are limited to 110 kilograms of petroleum or a maximum of 36.7 gallons.

To achieve the necessary force and efficacy, F1 motors boast a maximum thermal productivity surpassing 50 percent, markedly higher than a typical passenger car’s 35 percent thermal proficiency. Getting to that point necessitates an amalgamation of pre-chamber spark and an impressive 18 to 1 compression rate. The engine makers have multitudinous stunts they can use for both pre-chamber spark and to attaining the improved compression ratio which remain their proprietary info, forming a fundamental part of the secret concoction that characterizes modern F1 engines.
