When you purchase a Nissan, you need to know the engine specification for that model. Here are some basic specifications for the Nissan CR-engines, L28ET, L28DT, CR12DE, and CR14DE. These specifications should help you determine which model is best for you. Also, keep in mind that the L28ET has an electronic port fuel injection. If there is no letter in the engine specification, the engine is SOHC. Similarly, the MR16DDT engine has dual overhead camshafts, direct cylinder fuel injection, and a single turbocharger.
The Nissan CR-engine is a three-cylinder engine with low displacement. It is lightweight and compact, and produces excellent torque at medium speeds. It also delivers excellent fuel efficiency. The engine is relatively quiet, thanks to its fewer parts. This, in turn, reduces friction and improves combustion efficiency.
The HR12DDR engine uses a swirl control valve on the intake port to improve volumetric efficiency even under heavy EGR. It also implements a Miller cycle with internal EGR, and uses a CVTC system at the intake and exhaust ports. In addition, the piston has a low S/V even at the 13-compression ratio, making it more efficient in partial loads.
The CR14DE engine is manufactured from 2002 to 2013, and is mounted on several models, including the first generation of the Note hatchback. It is also a lightweight aluminum alloy engine that is equipped with an intake valve timing control system. This system continuously adjusts the intake valve phase according to driving conditions. It also helps increase low-range torque and improve high-speed range engine output. The intake valve timing system on the Nissan CR14DE engine is driven by a timing chain. The camshafts are 27.5mm in diameter and 224deg intake duration. They do not have hydraulic lifters, but instead use special valve lifters that adjust valve clearance.
The Nissan CR12DE engine is known to be highly fuel-efficient. It is made with an aluminum block and a five-bearing crankshaft supported system. Its cylinder bore and piston stroke are 71.0 mm and 78.3 mm, respectively. The engine is equipped with two compression rings and one oil-control ring.
Tuning the CR12DE’s engine is crucial for maximizing power. The intake manifold is responsible for drawing air from the filter during the suck phase. It also affects the delivery of fuel to the engine. Thankfully, there are a few aftermarket intake headers available. Other modifications such as larger valves, porting, and head flowing can increase the engine’s performance.
This engine has a variable vane turbo, which adjusts the angle of the vane to maximize peak torque. It also uses a twin scroll turbo, which directs exhaust gas into channels. This enhances the scavenging effect of the engine. And if that wasn’t enough, it comes with 4 bar air sensors to cope with large power gains.
The Nissan CR14DE engine specification is a compact and powerful gasoline engine. It features a 6-hole direct-injection system to improve the performance of this engine. This system minimizes oil dilution and improves homogeneity of combustion. This system also uses an exhaust continuously variable valve timing (EVT) and an internal EGR.
The Nissan CR14DE engine has a lightweight aluminum alloy block and a fivebearings supported crankshaft. It also has an EGR system to return some of the exhaust gas to the intake side, reducing fuel consumption and emission. However, it has several problems, ka24de most notable of which are loss of power and rough idle. The engine also contains ceramic dust from the EGR system that is absorbed by the engine and spreads through the engine’s oil system.
The high compression ratio helps increase thermal efficiency, but the engine tends to knock. Knock occurs when the piston’s surface temperature rises in response to compression. This makes it hard to address the problem without a boost system.
