The ports run down the outside of the cylinder wall into the crankcase which means there is a high probability that there is water in your crankcase.

Two stroke engines use ports on the side of the cylinder rather than valves at the top of a cylinder (4 - Stroke).

The Absolute Compression ratio is calculated from the point of volume where all valves are closed (because the engine is only making compression when all valves and / or ports are closed) to the volume of the cylinder at Top Center.

Compared with the last - gen TT RS, the 2.5 - liter turbo five in the new - for - 2018 model breathes better (thanks to new cylinder head with variable valve lift and duration timing on the exhaust cam), weighs nearly 60 pounds less (an aluminum block, magnesium upper sump, and other fat - reducing measures), and makes considerably more power, the byproduct of new port fuel injection and an increase in boost pressure from 18.1 to 19.6 psi.

This is not only a clean - sheet design, it also employs a revolutionary layout: cylinder heads rotated 180 degrees to relocate the exhaust ports to the center of the V and the intake ports to the heads» outboard flanks.

If as you say engine temps stayed normal then I would guess that this maybe excess coolant or oil that has run along the rocker cover or has ended up trapped in the recesses on the outside of the cylinder head, and this is burning off when it comes into contact with the hotter exhaust port area.

In a conventional two - stroke engine, the exhaust must open very early in the power stroke to enable the cylinder pressure to fall well below that of the incoming charge, in order to avoid spent gases entering the transfer ports and mixing with the fresh charge.

And because the injectors are sited as close to the intake ports as possible, there is very little time for fuel to drop out of the airstream before it enters the cylinder.

Variations of EFI used in Ford vehicles include: Multi-port Electronic Fuel Injection (MEFI) Also known as «direct port» injection, MEFI uses individual port - mounted injectors to deliver fuel directly to the intake inlet for each cylinder.

We can probably assume this powerplant was not one of the original Gen III V - 10s, though, because it has DOD — Displacement on Demand, with cylinder deactivation that turns the V - 10 into a five - cylinder for better fuel mileage — and variable valve timing like the Gen IV engines, as well as an LS3 / L92style rectangular port head.

To help with the explanation of the second component, Figure Two shows traces of in - cylinder pressure (black), port pressure at the intake valve (light blue) and port pressure at the exhaust valve (red), taken from a simulation of a high BMEP engine operating near the optimum tuning point for both intake and exhaust.

Lexus took a series series of detailed design and engineering measures to fine tune the performance of the 3.5 - liter V6 gasoline engine featured in the LC 500h's full hybrid powertrain, including a reduction in the diameter of the cylinder intake port to increase flow speed and efficiency.

Heads of the cylinder block were also updated, diameters of inlet and outlet ports increased.

The layout of a branch intake port inside the cylinder head was chosen to have only one intake channel for two cylinders.

A lightweight cylinder head made of pressure - cast aluminum alloy uses front - located exhaust ports that provide greater freedom in the layout of the close - coupled catalytic converter which mounts directly to the cylinder head.

The twin - scroll design separates the cylinders whose exhaust gas pulses interfere with each other, resulting in improved pressure distribution in the exhaust ports and a more efficient delivery of exhaust gas energy to the turbocharger's turbine for quick and smooth responsiveness.

The twin - scroll design separates the cylinders whose exhaust gas pulses interfere with each other, resulting in improved pressure distribution in the exhaust ports and a more efficient delivery of exhaust gas energy to the turbocharger's turbine.

The twin - scroll turbocharger design has several other advantages over traditional, single - scroll turbocharging systems, including: • Improved combustion efficiency • Low engine - speed efficiency • Kinetic exhaust gas energy is not wasted or trapped • Cooler cylinder temperatures • Lower exhaust temperatures • Leaner air / fuel ratio • Better pressure distribution in the exhaust ports and more efficient delivery of exhaust gas energy to the turbocharger's turbine Veloster's twin - scroll turbo has superior handling of exhaust gas separation at the turbine leading to improved low - end torque and faster transient torque response.

Among the upgrades included in the tuning package are a larger supercharger with 14 psi of boost pressure, upgraded camshafts, ported factory cylinder heads, long - tube stainless steel headers, custom engine management and a high - flow air induction system.

With 600 horsepower and 664 pound - feet of torque, this twin - scroll - turbo - fed engine is substantially more powerful, yet it's also over 60 pounds lighter and more fuel efficient, thanks to cylinder deactivation, port - and direct - injection, and stop / start technology.

Apart from the mounting positions of the fuel injectors, the cylinder head has conventional port and combustion chamber designs, although both are optimized for direct injection and high boost pressures.

A series of detailed design and engineering measures have been taken to fine tune performance, including a reduction in the diameter of the cylinder intake port to increase flow speed and efficiency, contributing to excellent power output and a feeling of continuous acceleration.

* The answer: features like Ford - first port fuel and direct injection (PFDI) with two injectors per cylinder (one in the air intake port, another inside the cylinder), plus upper block and cylinders made of the high - strength compacted graphite iron used in the Super Duty ® 6.7 L Power Stroke ® Turbo Diesel.

Chevrolet Performance engineers developed the high - performance camshaft - and - cylinder - head package in - house, leveraging the design elements of the LT1's advanced combustion system to channel airflow through the optimized cylinder head ports.

Fuel injection on the V6 will be a combination of direct injection into the cylinder and traditional port injection, called D - 4S technology.
