How does an engine contribute to a car's powertrain?

The powertrain in a vehicle is the system responsible for generating power and delivering it to the wheels to propel the vehicle forward. The operation of a powertrain can vary depending on whether the vehicle is powered by an internal combustion engine (ICE) or an electric motor (in the case of electric vehicles). Here's a general overview of how a powertrain works in both types of vehicles:

Internal Combustion Engine (ICE) Vehicle - Combustion Process: In an ICE vehicle, the powertrain starts with the combustion process in the engine. Fuel (gasoline or diesel) mixes with air in the combustion chamber and is ignited by spark plugs (in gasoline engines) or compression (in diesel engines).

Power Generation: The combustion process generates energy in the form of mechanical power, causing pistons to move up and down within the cylinders of the engine. This motion drives the crankshaft, converting linear motion into rotational motion.

Transmission: The rotational motion from the crankshaft is transmitted to the transmission, which consists of gears that allow the driver to select different ratios (speeds). This enables the engine to operate efficiently across a range of vehicle speeds.

Drivetrain: The transmission sends power to the drivetrain components, including the driveshaft, differential, and axles, which transfer power to the wheels. The differential allows the wheels to rotate at different speeds, enabling smooth turns.

Wheel Movement: The power transmitted through the drivetrain causes the wheels to rotate, propelling the vehicle forward or backward depending on the gear selection and throttle input from the driver.

Electric Vehicle (EV) -

Battery Pack: The primary source of power for the EV, storing electricity in chemical form.Powers the electric motor and provides electricity for all electronic devices within the EV.

Battery Management System (BMS): Monitors battery cell conditions, including voltage, current, temperature, and state of charge (SoC).It protects the battery against overcharging, deep discharging, and overheating and helps balance the charge across cells. Ensures optimal performance and longevity of the battery by regulating its environment.

Inverter: Converts DC from the battery pack into AC to drive the electric motor.Adjusts the frequency and amplitude of the AC output to control the motor’s speed and torque. Critical for translating electrical energy into mechanical energy efficiently.

Onboard Charger: Facilitates the conversion of external AC (from the grid) to DC to charge the battery pack. Integrated within the vehicle, allowing for charging from standard electrical outlets or specialized EV charging stations. Manages charging rate based on battery status to ensure safe and efficient charging.

DC-DC Converter: Steps down the high-voltage DC from the battery pack to the lower-voltage DC needed for the vehicle's auxiliary systems, such as lighting, infotainment, and climate control. Ensures compatibility between the high-voltage battery system and low-voltage electronic components.

Electric Motor: Converts electrical energy into mechanical energy to propel the vehicle. It can be of various types, such as induction motors or permanent magnet synchronous motors, each offering different efficiencies and characteristics. Typically provides instant torque, resulting in rapid acceleration.

Vehicle Control Unit (VCU): The central computer or electronic control unit (ECU) that governs the EV's systems. Processes inputs from the vehicle’s sensors and driver inputs to manage power delivery, regenerative braking, and vehicle dynamics. Ensures optimal performance, energy efficiency, and safety.

Power Distribution Unit (PDU): Manages electrical power distribution from the battery to the EV’s various systems. Ensures that components such as the electric motor, onboard charger, and DC-DC converter receive the power they need to operate efficiently. Protects the vehicle's electrical systems by regulating current flow and preventing electrical faults.

In both ICE vehicles and EVs, the powertrain's components work together to convert energy into motion, enabling the vehicle to move efficiently and effectively. However, the specific technologies and processes involved differ significantly between the two propulsion systems.

hard to explain to people like yeah i do pretty much only hang out with guys and i don’t really know how to interact with girls but it’s not out of internalized misogyny it’s because i work in automotive and studied mechanical engineering and therefore rarely see or talk to irl women i’m not directly related to and therefore like many engineers, i also have no clue how to talk to women
