CPC v2.1 Code: 43121

About spark-ignition reciprocating internal combustion piston engines, of a cylinder capacity not exceeding 1000 cc

cpc code 43121 covers the production of spark-ignition reciprocating internal combustion piston engines with a cylinder capacity not exceeding 1000 cc. These compact engines are widely used in a variety of applications, from small motorcycles and scooters to lawn mowers and portable generators. They play a crucial role in the transportation and power generation sectors, contributing to the broader economy through their versatility and efficiency.

Production process

The production of cpc code 43121 engines typically involves several key steps. First, the engine block and cylinder head are cast from aluminum or other lightweight alloys. The pistons, crankshaft, and other moving components are then precisely machined and assembled. The fuel delivery system, including the carburetor or fuel injection system, is installed, and the ignition system, including the spark plugs and ignition coils, is integrated. Finally, the engine is tested, tuned, and prepared for installation in the final product.

Production inputs

The main inputs required for the production of cpc code 43121 engines include aluminum or other lightweight alloy castings for the engine block and cylinder head, high-strength steel for the crankshaft and other moving components, and various electronic and mechanical components for the fuel delivery and ignition systems. Additionally, specialized machinery and tooling are required for the precise machining and assembly of these compact engines.
