Nissan recalls nearly 20,000 NV vans over gearshift issue

Nissan is recalling 18,800 NV vans built between December 20, 2010 and January 4, 2013. Certain 2012 and 2013 models equipped with a steering-column-mounted transmission shift levers may have been built with improperly installed shift mechanisms.
If the NV's gear selector plate lock clip wasn't installed correctly, normal road vibration could result in a gear position indicator that does not match the actual gear selection. As a result, when the driver selects 'park,' the transmission could still be in gear or in neutral, and roll away. The National Highway Traffic Safety Administration says this condition greatly increased the risk of accident and injury.
Nissan will inspect the gear selector lock clip and replace the part if necessary free of charge. Owners can expect to be notified once the recall campaign begins on April 8, 2013. Read the full recall notice below for more information.

What to expect from the Japanese trial of Nissan and Greg Kelly

TOKYO — The criminal trial against Japanese automaker Nissan and its former executive Greg Kelly will open in Tokyo District Court on Tuesday. ItÂ’s the latest chapter in the unfolding scandal of Carlos Ghosn, a superstar at Nissan until he and Kelly were arrested in late 2018. Five questions and answers about the trial: Q: WHAT ARE THE ALLEGATIONS? A: The charges center around KellyÂ’s role in alleged under-reporting of GhosnÂ’s future compensation by about 9 billion yen ($85 million), a violation of financial laws. Kelly says he is innocent. Nissan, which is also similarly charged, has already acknowledged guilt, made corrections to the compensation documents submitted to the authorities, and has started paying a 2.4 billion yen ($22.6 million) fine. Q: WHAT HAPPENS TO GHOSN? A: Probably nothing. He skipped bail late last year and is now in Lebanon, which has no extradition treaty with Japan. Two Americans, Michael Taylor and his son Peter Taylor are being held in Massachusetts without bail, suspected of having helped Ghosn escape by hiding in a box on a private jet. A U.S. judge recently approved their extradition to Japan. The case is now before the U.S. State Department. Q: HOW DO CRIMINAL TRIALS PROCEED IN JAPAN? A: The trial, before a panel of three judges, is expected to take about a year. There is no jury. Juries are selected only for extremely serious cases in Japan, such as murder. In principle, there are no plea bargains although backroom deals are made all the time. Closed pre-trial sessions are held ahead of the trialÂ’s opening, often for months before the real trial begins. Japan's legal system has come under fire from both within and outside the country as “hostage justice” because suspects often are held for months and interrogated without a lawyer present, often leading to false confessions, according to critics. Q: WHAT ARE KELLYÂ’S CHANCES? A: More than 99% of criminal trials in Japan result in a conviction. Japanese Justice Minister Masako Mori, in an online presentation in English hosted by the Japanese Embassy in the U.S., argued the conviction rate is so high because Japan prosecutes only about a third of the cases that come up, choosing only those that “result in guilty verdicts.” She insisted there is a “presumption of innocence.” She declined comment on KellyÂ’s case.

Infiniti's new VC-T changes the rules of small turbocharged engines

The upcoming Infiniti QX50 crossover does not get our pulse racing, no matter how shapely the QX Sport Inspiration concept that previews it may be. No midsize SUV does, to be fair. But it has something special under the hood – the world's first production variable-compression-ratio engine. That means the QX50's 2.0-liter turbo four, which makes 268 horsepower and 288 pound-feet of torque, will have up to 27 percent better fuel economy. Here's how it works. The trend of moving to smaller, turbocharged engines carries with it one big falsehood. Under low load when the turbo isn't needed, these engines are less efficient than an equivalent engine without a turbo because of the low compression ratio the turbo requires. That is, if you never need the extra power, you're wasting fuel. Turbocharged (and supercharged) engines use a lower compression ratio to prevent detonation. When you force extra air in a cylinder and mix it with fuel, it's more likely to prematurely go boom. Lowering the compression ratio prevents this problem, but it's less efficient. Infiniti's VC-T promises the best of both worlds, with a compression ratio that ranges from 8.0:1 for high-power turbo needs to a 14.0:1 ratio for fuel-sipping efficiency. At its heart the VC-T engine is a simple idea, but it's complicated to explain. Consider yourself warned. The photo below from Infiniti serves as a good visual overview. For the truly nerdy, this patent application covers the mechanical concept. Instead of having the pistons connected to the crankshaft, Infiniti's engine has a pivot arm with a connection on each end. One end connects to the piston, the other connects to a second lower shaft, which is controlled by an actuator arm. At any given time the engine's pistons move up and down according to the lobes on the crankshaft. But the actuator arm can change the angle of the pivot arm up and down. That is, the pistons still move in the same motion with the same stroke, but phase the entire stroke up or down. Move the pivot up and there's less room at the top, which means a higher compression ratio. Move the pivot down and the compression ratio goes down, too. As an added bonus, the lower shaft eliminates the need for counter-rotating balance shafts. Infiniti says this system works constantly and can vary the compression ratio to any number between 8:1 and 14:1. It also uses electronic variable valve timing on the intake valves to switch into Atkinson-cycle combustion for greater efficiency.
