What is ESP (Electronic Stability Program)? The ESP system is designed to enhance vehicle stability and prevent skidding or loss of control, especially during sudden maneuvers or on slippery surfaces. It works by monitoring various sensors, including wheel speed, steering angle, and lateral acceleration, and selectively applying brakes to individual wheels or reducing engine power to maintain stability. What is BAS (Brake Assist System)? The BAS system assists the driver in emergency braking situations by automatically applying maximum braking force when it detects a panic stop. This helps to reduce stopping distances and potentially prevent collisions . What Does the ESP…

What is a Pitman Arm? The Pitman arm plays a vital role in a vehicle’s steering mechanism. It acts as a pivoting lever, linking the steering gearbox to the steering linkage. This component converts the rotational motion from the steering wheel into linear motion, which is transmitted to the tie rods and then to the wheels. The Pitman arm’s main function is to enable the wheels to turn, translating steering wheel input into precise vehicle movement. Function of the Pitman Arm The Pitman arm’s primary function is to convert angular motion from the steering gearbox into linear motion, needed to…

What is a Gel Battery? A gel battery is a type of lead-acid battery that uses a semi-solid gel electrolyte instead of a liquid electrolyte solution. The key components are: The gel electrolyte is formed by adding fumed silica to sulfuric acid, which creates a three-dimensional silica network that immobilizes the acid. This prevents acid leakage and spillage compared to traditional flooded lead-acid batteries. Gel Battery Manufacturing Process The manufacturing process involves layering the positive and negative electrodes with the gel electrolyte, encasing the battery in a laminated film, and applying heat and pressure. This step is crucial to ensure…
What Is a LFP Battery? Lithium iron phosphate (LiFePO4 or LFP) batteries are a type of lithium-ion battery that uses LiFePO4 as the cathode material. LFP batteries have several advantages over other lithium-ion battery chemistries, including: However, LFP batteries also have some limitations, such as lower energy density (170 mAh/g theoretical capacity) and lower electrical conductivity compared to other cathode materials LFP Battery Core Benefits and Characteristics Core Benefits of LFP Batteries Key Characteristics of LFP Batteries Pros and Cons of LFP Batteries Pros of LFP Batteries Cons of LFP Batteries LFP Battery Best Practices for Use and Care LFP…
What is DOHC? DOHC is a type of engine configuration in which two camshafts are used to operate the intake and exhaust valves, with one camshaft dedicated to the intake valves and the other to the exhaust valves. This design is commonly found in modern high-performance engines, particularly in the automotive industry. How DOHC Engines Work In a DOHC engine, the camshafts are positioned above the cylinder head, with one camshaft located above the intake valves and the other above the exhaust valves. Each camshaft has a series of lobes that actuate the corresponding valves through rocker arms or other…
Introduction When it comes to automotive engines, SOHC vs. DOHC configurations represent two distinct approaches to valve control and performance. While both designs share the goal of efficiently managing engine airflow, their differences have a significant impact on power, fuel efficiency, and complexity. SOHC (Single Overhead Camshaft) engines, with a single camshaft per cylinder bank, are known for their simplicity, cost-effectiveness, and reliable performance in everyday vehicles. In contrast, DOHC (Dual Overhead Camshaft) engines feature dual camshafts, offering precise valve timing, increased horsepower, and smoother operation—making them the preferred choice for high-performance and modern vehicles. Understanding these distinctions can help…
What is a Serpentine Belt?

What Is a NiMH Battery? The Nickel-metal hydride (NiMH) battery represents an evolution of nickel-hydrogen (Ni-H2) batteries, replacing hydrogen with metal hydrides to avoid the danger of working with high-pressure gases.They have replaced NiCd batteries, which contain toxic cadmium, along with lithium-ion batteries (LIBs). NiMH batteries entered the market in 1991, introduced by the Japanese company Sanyo. Components and Working Principles The main components of a NiMH battery are the anode (hydrogen storage alloy powder), cathode (nickel coated with nickel hydroxide), electrolyte (typically KOH), separator, and steel case. The overall electrochemical reaction is: Charge: NiOOH + M + e- → Ni(OH)2…
