A Saturn that actually looks pretty good would turn really awful if suddenly
it stopped because of fuel loss. Fuel is the lifeblood of a vehicle. The inadequate
supply of this auto product to the system of the machine would consequently impair
the whole operation. Whereas, its adequacy would readily provide enough source
of power for a performance that showcases the true prowess of the vehicle's engineering.
Delivery of fuel to the engine system is taken cared by the auto component called
the intake manifold.
The Saturn intake manifold is an engine part, a system of passages that supplies
fuel and air to the cylinders through runner ports. It is also known as the inlet
manifold of the induction system. The air that enters the cylinder is being mixed
with the fuel. This mixture is meant for processing of the power source through
combustion and ultimately in power generation. Aside from acting as passage for
the two important elements in combustion process, the intake manifold is the one
that charges the cylinders with even strength and quality. This way, efficient
engine operation is achieved, bringing then smooth performance. A Saturn that
features multi point injected engines also lays responsibility of holding the
fuel injectors to the intake manifold.
Saturn intake manifolds vary in designs. Each design is applicable only to certain
engine types. There are tunnel ram, cross ram, open plenum, divided single plane,
single plane with partial divider plate and isolated runner intake manifold. Their
variations according to type and application also led to differences of locations
wherein the operation effectiveness is as well affected. V8 engines mount their
intake manifolds between the cylinder heads. Others are found between the carburetor
and the cylinder head. L-head engines have their intake manifolds integrated to
the side of the block, while I-head manifolds are typically bolted to the cylinder
The quality of intake manifold performance depends on its design. In this aspect,
fuel charge plays a large part. Dry fuel vapor is an ideal form of fuel charge.
But in modern intake manifold designs, fuel charge efficiently works only when
the temperature is high. This is because most types of fuels today prevent the
kind of fuel reaction. The problem then rests on the effect of too high temperature
that's capable of reducing the power of the engine with the heat-expanded fuel
charge. By depositing some fuel on the walls of the cylinders and manifold vents
from which modern designs of intake manifolds are based, the effect of condensed
fuel is reduced to a minimum amount.
