DPF (Diesel Particulate Filter)
A filter in the exhaust of diesel engines that traps soot particles. It fills up especially with short-distance driving; when full, the engine loses power and a warning light may come on.

Regeneration
Cleaning of the DPF by burning off the accumulated soot at high exhaust temperature. It happens automatically during longer drives at a steady engine speed.
Injector
The component that sprays fuel into the combustion chamber as a fine mist. Deposits on its tip disturb the spray pattern, causing rough idling, power loss and higher fuel consumption.
Cetane Number
A measure of how readily diesel fuel ignites. Fuel with a higher cetane number gives easier starting and quieter, smoother combustion.
Engine Sludge and Carbon Deposits
Dark, sticky residue that forms inside the engine as oil degrades from overdue changes and combustion by-products build up. It narrows oil passages and weakens lubrication.
Antifreeze (Coolant)
The fluid that carries engine heat to the radiator and prevents freezing and boiling. Over time its inhibitors wear out and scale, rust and sludge begin to form.
Expansion Tank
The translucent plastic reservoir that coolant flows into as it expands when hot. The coolant level is checked here; its cap must never be opened while the engine is hot.
Evaporator
The core behind the dashboard that cools the air in the A/C system. Being damp and dark, it easily harbours bacteria and mould and is the main source of bad A/C odours.
Cabin (Pollen) Filter
The filter that traps dust, pollen and particles in the air entering the cabin. Replacing it together with the A/C clean keeps odours from returning quickly.
Oxidation (Contact Corrosion)
A thin layer that forms on electrical contacts exposed to moisture and air, reducing conductivity. A common cause of faulty sensors, flickering lights and equipment that stops working.
MoS2 (Molybdenum Disulphide)
A solid lubricant that keeps surfaces sliding even under high pressure and temperature. In rust removers it leaves a protective film on the threads after the bolt is freed.
Liquid Gasket (RTV Silicone)
Silicone applied from a tube that cures at room temperature with moisture in the air and turns into a flexible gasket. On uneven flanges it can seal better than a pre-cut gasket.
Curing
The chemical hardening through which liquid gaskets and adhesives reach their final strength. Even if the surface dries in minutes, full cure can take hours; the part should not be loaded in the meantime.
Cyanoacrylate and Activator
Cyanoacrylate is the adhesive commonly known as "instant glue". An activator spray cuts setting time to seconds, especially on porous surfaces such as MDF and wood.
Vinyl
A plastic-based trim material widely used on dashboards, door panels and consoles. Sun and heat gradually fade and harden it; regular care slows this down.
pH-Neutral Shampoo
A car wash shampoo that is neither acidic nor alkaline, with a pH around 7. It removes dirt without harming the paint, waxes or protective coatings.
