By John Cousins May 16, in Guest. I wanted a forever car and i'm having this car properly engineered in the hope that it's a perfect mix of old vs new with quiet, mild road manners but plenty of punch when asked. The engine I have purchased has come with the factory ECU but obviously being from i'm expecting headaches with regard to the ECU not seeing multiple CAN nodes and probably de-rating the engine, or worse still, not allowing it to start at all. That's before we get to the whole immobiliser side of things! Just wondering if anyone has played around with a Honda GDI engine and a Link or would I be kind of pioneering my way through this? Obviously passing an emission check is critical for this build but it's not the full check, I think WA requires just requires the vehicle to pass a 5 gas analysis.

L15b7 engine

The L15B7 is a 1. The engine is a result of Honda's downsizing strategy that involves using small displacement units in conjunction with a turbocharger to overcome the power problem. So, the 1. The manufacturer already began offering the 1. Let's take a closer look at what makes the Honda 1. The engine uses an aluminum open-deck cylinder block and aluminum cylinder head. The engine block is equipped with lightweight steel connecting rods heat-forged for higher strength to withstand high loads. There are also new cavity-shaped pistons with an optimized skirt design to minimize vibration and friction and increase operating efficiency. The manufacturers applied plateau honing grinding process for cylinder walls to reduce friction between pistons and cylinders even more. Pistons are cooled by oil spray jets directed at the bottom of the piston. The head design includes four valves for each cylinder and DOHC dual overhead cam driven by the timing chain. The intake and exhaust camshafts are equipped with actuators of the VTC. Each multi-hole direct fuel injector is placed between two intake valves; the spark plug is on top in the center of a combustion chamber. The cylinder head has high tumble intake ports tumble ratio is 1. The 1.

As part of the L15b7 engine. The 1. Generally, mapping points are denser in the lower engine speeds and load areas of operation.

Federal government websites often end in. The site is secure. As part of the U. The test method involved installing the engine and its CVT in an engine dynamometer test cell with the engine wiring harness tethered to its vehicle parked outside the test cell. This paper documents the test results for idle, low, medium and high load engine operation, as well as motoring torque, wide-open throttle torque and fuel consumption during transient operation using both EPA Tier 2 and Tier 3 test fuels. Particular attention is given to characterizing enrichment control during high load engine operation. The design and performance of the 1.

It took Honda nine generations of the Civic to finally concede that Boost is Best! Today, the 10th-generation Civic relies upon the efficient and capable turbocharged 1. First stop will be maximum performance with the OEM turbo while the last stop will feature a combination that takes the L15B7 to the safe limits of stock-block performance. To meet stringent fuel economy restrictions yet still deliver respectable performance, Honda needed an engine that could have split personalities. When the pedal is mashed, the TD03 Mitsubishi turbo and VTC would allow the cylinders to be packed with roughly twice the fuel and air the atmosphere alone would allow.

L15b7 engine

One of the latest in a long line of Honda engines renowned for its power, efficiency, and reliability, the 1. Since the 1. Today the latest versions of the 1. Engine Internals To minimize weight, the engine block is die-cast aluminum. Individual reinforced main bearing caps add strength. Cast-in iron cylinder liners provide long-lasting durability. Each journal on the lightweight forged-steel crankshaft is micropolished to reduce internal friction. Twin oil jets directed at the underside of each piston crown keep the pistons cool to help prevent detonation, and ion-plated piston rings help reduce friction for greater operating efficiency. This eliminates the need for a separate exhaust manifold, reducing weight and complexity.

A cold engine can develop condensation and excess fuel vapors that travel down into the crankcase and mix with the engine oil in the oil pan. Since the 1. The auxiliary transmission mounted between the CVT and the dynamometer was needed to step down the CVT output torque so it could be absorbed by the dynamometer. Oberg Honda Malaysia Racing Team. Your high pressure fuel pump is a positive displacement pump and petrol is basically not compressible. These results will be used later on to develop brake-specific fuel consumption BSFC and BTE maps suitable for use in vehicle simulation models. Test cell automation hardware and software system that controls the dynamometer and some engine controls; collects test cell data; master data logger. Once the roughly 30 seconds of transient data have been collected for all of the high load points, the captured data streams must be post- processed to determine the specific final results. John Cousins Posted May 16, Have product fitment questions?

The L-series is a compact inline-four engine created by Honda , introduced in with the Honda Fit. It has 1. Two different valvetrains are present on this engine series.

This paper documents the test results for idle, low, medium and high load engine operation, as well as motoring torque, wide-open throttle torque and fuel consumption during transient operation using both EPA Tier 2 and Tier 3 test fuels. The blue line in the bottom chart in Figure 7 shows the change in exhaust lambda air-fuel equivalence ratio. Last accessed onJanuary 3, To reduce the temperature of intake air compressed and heated by the turbocharger, Honda's 1. Back to Top. The Ford EcoBoost 1. Since the ALPHA model computes combined vehicle CO2 and fuel consumption using the light- to moderate-load regulatory city and highway drive cycles, EPA uses data from the initial interval when subsequently building the complete engine maps for use in ALPHA vehicle simulations. Data Collection — For each data point, the data are logged continuously at Hz while the engine torque is ramping up to the desired torque value and while operation is held at that point for 30 seconds. BTE map generated from the data published by Honda for the 1. Thank you guys so much. Definitely looking forward to the more robust components. The actual temperature for each sampled data point is recorded with each data point. However, the Sport and Sport Touring models were equipped with a variation of the engine L15BA that produces horsepower SAE net 6, rpm running at the same boost levels.
