Here's what we know about the 2021 Nissan Z

“…

  • The next-generation Nissan Z sports car is finally on the horizon, and here's what we know about it.

  • It will be the long-awaited replacement for the ancient 370Z, which has been on sale since 2009 with few updates.

  • We expect the new Z to debut sometime this year as a 2021 model.

The wait for a new Nissan Z sports car is almost over. As we approach the arrival of a replacement for the long-in-the-tooth 370Z—finally!—the rumor mill is running at full capacity, giving us some exciting tidbits about the new two-seater's powertrains, platform, and design. Here is what we expect from the new Z.

Twin-Turbo V-6 Power

The most powerful engine currently in Nissan and Infiniti's lineup is the twin-turbocharged 3.0-liter…”

WHAT IS OIL AERATION?
WHAT IS OIL AERATION?

Air contamination in oil is a serious condition. There are five problems associated with aerated oil that can be deadly to lubrication components, like oil pumps.

WAYS TO MEASURE OIL AERATION
WAYS TO MEASURE OIL AERATION

With proper measurements one can quantify the susceptibility of one's design or component to the negative effects of aeration.

HOW TO INTRODUCE OIL AERATION
HOW TO INTRODUCE OIL AERATION

There are a number of ways to introduce air into the oil to obtain a certain level of aeration. There are two predominant methods for achieving oil aeration: suction port t-fitting and direct injection.

DOES AERATION LEAD TO CAVITATION?
DOES AERATION LEAD TO CAVITATION?

Apart from the ingress of debris, the greatest danger to any design of a pump is cavitation. The phenomenon can be found in centrifugal (i.e. impeller) or positive displacement (i.e. gear, gerotor or vane) pumps, in both oil and coolant applications. Excessive cavitation can lead to erosion damage. It is important to understand how cavitation occurs as there are some misconceptions and confusion on this topic.

CONTAMINANTS WREAK HAVOC IN OIL
CONTAMINANTS WREAK HAVOC IN OIL

The major purpose of lubrication oil is to provide low bearing friction, to transfer heat and to protect components from corrosion. Contaminants will affect the oil’s ability to meet these requirements.

OIL AERATION HURTS EFFICIENCY
OIL AERATION HURTS EFFICIENCY

Many OEMs are battling to improve vehicle durability, increase efficiency and reduce noise, but are struggling to find the answers. Unfortunately, many of the recent design trend are forcing higher aeration levels, and far too many OEMs are unaware. 

In the pursuit of greater efficiency, many OEMs are making design decisions that may amplify the effects of oil aeration. Air bubbles may seem benign, but they can detrimentally affect the performance and durability of engines, drivelines and hydraulic equipment.  

EV Component Testing Challenges - From 12 to 800VDC
EV Component Testing Challenges - From 12 to 800VDC

As the global interest for clean energy alternatives increases within the automotive industry, so does the requirement of efficiently storing electricity. The latest trends in electric vehicle technology have led to the development of high-voltage storage solutions, all backed by the need for increased efficiency and quicker charge times.

Engine Oil Pump Production Testing - CASE STUDY
Engine Oil Pump Production Testing - CASE STUDY

ATA Inc. was awarded a project from an existing client to build test systems for production verification testing on six different engine oil pump models. We delivered on the client's needs for an accurate and interchangeable tool to verify pump performance and functionality using a grouping layout for the individual test cells, and by employing laser marking stations.

Torsional Vibration in shafts and other mechanical systems

The torsional vibration of a crank or motor shaft is an important factor in the suitability and reliability of a system design. Finite element modelling can predict the natural vibration and forced vibration based on the expected harmonics and speeds. However, modelling can only go so far, and oftentimes a measurement setup is required, such as ENSURE, for physical validation of the key assumptions.

Pulsation in pipes and other hydraulic systems

Pumping and system pulsations are an important factor in the suitability and reliability of a design. Finite element modelling can predict the natural waves and forced waves based on the expected pump harmonics, geometries and speeds. However, modelling can only go so far, and oftentimes a measurement setup is required, such as ENSURE, for physical validation of the key assumptions.
