For use on pre-pollution controlled vehicles only. Cylinder Head Specifications: Combustion chamber volume: 70cc / 64cc, Intake runner volume: 185cc, 

Head bolts play a vital role in the sealing of the combustion chamber, oil/coolant channels and ambient air. Other benefits include pre-applied sealant to the 

Heat up area around bore on the head with heat gun. The term indirect injection refers to a fuel injection system where fuel is not directly injected into the combustion chamber. An indirect injection diesel engine delivers fuel into a chamber off the combustion chamber, called a pre-combustion chamber, where combustion begins and then spreads into the main combustion chamber. Pre-chamber spark ignition (PCSI) combustion is an emerging lean-burn combustion mode capable of extending the lean operation limit of an engine.

the raw meal that was finely dispersed in the flue gas stream of the rotary kiln is calcined in the entrained flow and receives the necessary energy from a similarly finely dispersed fuel - from coal for example, that is being simultaneously combusted there.

This is the type of pre-chamber Maserati uses, and Pre-chamber jet ignition enables stable, highly dilute combustion by both increasing the ignition energy present in the system and distributing it throughout the combustion chamber. Previous work by the authors have shown that jet ignition produces 15–25% increases in thermal efficiency over baseline SI engines with only relatively minor changes to engine architecture. The potential of pre-chamber ignition systems in modern combustion engines is evaluated in various publications [3, 5,21].

Normally, this mixture wouldn't have enough fuel to ignite on its combustion at lambda > 2.2 by leveraging fuel-rich mixture inside the pre-chamber • Lean limit extension beyond lambda ~ 1.8 required fuel-rich mixture inside the pre-chamber, but strength of rich mixture had no observed influence within the flammability limits Pre-Combustion Chamber The pre-combustion chamber is usually used in high-speed engines. There are two combustion chambers one is auxiliary combustion chamber and the other is the main combustion chamber.

The combustion pre-chamber is connect to main chamber by a throat. According to 14.5 cc volume, sphere diameter has determined as 30 mm. Pre-combustion chamber cross section demonstrates in Figure 3.

Pre-chamber spark ignition (PCSI) combustion is an emerging lean-burn combustion mode capable of extending the lean operation limit of an engine. The favorable characteristic of short combustion duration at the lean condition of PCSI results in high efficiencies compared to conventional spark ignition combustion. Active pre-chambers contain a spark plug and fuel injector, and ignite after a lean air-fuel mixture is brought into the cylinder. Normally, this mixture wouldn't have enough fuel to ignite on its combustion at lambda > 2.2 by leveraging fuel-rich mixture inside the pre-chamber • Lean limit extension beyond lambda ~ 1.8 required fuel-rich mixture inside the pre-chamber, but strength of rich mixture had no observed influence within the flammability limits Pre-Combustion Chamber The pre-combustion chamber is usually used in high-speed engines. There are two combustion chambers one is auxiliary combustion chamber and the other is the main combustion chamber.
