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. Also keen to know what electronic dash displays play well with link as it's probably just easier to swap to a completely new display than make the existing dash work with the new 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.

Schematic of dynamometer test cell and the engine sensor locations corresponding to the identified systems.

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 process allows the engine to have more power while keeping fuel consumption low, thanks to the better gasoline utilization. Emissions are also reduced. The i-DSI engines have two to five valves per cylinder and a modest redline of only 6, rpm, but reach maximum torque at mid-range rpm, allowing for better performance without having to rev the engine at high speeds.

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.

Honda L15 engines are a variant of the vast L-series of engines. It appears in many models of Honda cars and created an avenue for compact and subcompact engine cars. However, L15 engines took all of that right in the face and proved that they are worthy of praise, and their different and diverse versions say a lot about what L15 engines can offer. This L-series feature ideas that eclipsed its previous but well-established D-series engine, eventually replacing them down the road. L series are lighter, smaller, narrower, and have a better fuel economy while attaining lower emission levels. L series engines are smaller and thinner compared to the previous D series designs, especially when juxtaposed with the 1. L series engines have a much more compact SOHC cylinder head design.

Both steady-state and transient engine test data are collected during the benchmark testing. Figure 8. The Miller cycle is expected to be applied to increasing numbers of boosted engines as development engineers use boosting to overcome reduced power density less charge per unit exhaust stroke and implement various methods of increasing charge motion e. Date Range. Although only limited information on this engine is available, it is likely that the supercharger is used in part to drive external EGR and may also be used to increase peak BMEP. Type of internal combustion engine. Effect of different fuels on BTE at rpm all points are in stoichiometric operation. The efficiency of the Honda 1. Downsized boosted engines are a key technology being used today to meet performance targets as well as GHG and fuel economy standards. Honda Motor. Special care is required for measuring engine torque and for measurements from other sensors that are sensitive to engine cyclical dynamics. When engine speed is high and engine load is also high, such as during full-throttle acceleration, the amount of valve overlap is reduced to increase engine output by improving both intake and scavenging.

Figure 15 also contains an image of the energy weighted operational cloud for this engine in a vintage mid-sized example vehicle driving over the combined regulatory cycles. Two different valvetrains are present on this engine series. Figure A6. As intake air is compressed by the turbo, it heats up, and the intercooler helps reduce that temperature, making it denser and improving performance. The new test procedures developed, along with traditional steady-state test procedures and low-speed test procedures incorporating a transmission, enabled the testing of the engine over its full operating range, including idle, low to high load at stoichiometric and high load with commanded fuel enrichment. Once the engine is fully warmed up, fuel is injected during the intake stroke for maximum power and fuel efficiency. PMC Copyright notice. Later turbo implementations improved on this, and thus the Ford EcoBoost 1. Today the latest versions of the 1. Special measurement of fuel consumption during transient operation: Typically, when benchmarking an engine, steady-state operation allows for the straightforward measurement of fuel consumption either by a fuel flow meter or by exhaust emissions. To reduce the temperature of intake air compressed and heated by the turbocharger, Honda's 1. Article Talk. The head design includes four valves for each cylinder and DOHC dual overhead cam driven by the timing chain. Ten of the technologies, represented by the columns with red text titles in the Table 9 , are either present in the specific engine the row , or they are absent. Both laboratory test data and ALPHA simulation results continue to be used to support evaluation of light-duty vehicle fuel economy and greenhouse gas emissions standards and are also being used to evaluate the gap between laboratory and actual in-use emissions.
